So much about aviation is covered incorrectly in the media that AI tends to retrieve the incorrect stuff as gospel. I've spent a lifetime around aircraft / aviation. Hardly any media civerage about aviation is anywhere near true. Quite a few of the books used as references by AI are nothing more than collections of stories with the attendant embellishment that always creeps in when stories are told.
When I have used AI to get things about WWII aviation, it is about 40-60% accurate if I'm lucky. Many times I'm not so lucky. AI doesn't sift through text for accuracy; it sifts for published contant regardless of accuracy. It basically outputs what it finds written in text that is avaiable for perusal.
It's kind of like a self-driving car. The "goodness" of the AI driver is completely dependent upon the programmer or team that writes the software, and they're only as good as the things they anticipate might happen in traffic. If anything happens they have not anticipated, the result is a toss up as to whether or not the response is good. Witness the stupid things done by self-driving taxis fairly recently.
A large factor in AI-supported arguments is that the LLM is usually coded to also agree with whoever is writing the prompt and doesn't really have any standard for intellectual consistency either. Also note how the specific anecdote that was started with was relating to a completely different author by the name of Ichimuru.
I should admit that I am no expert on the history of the Central Pacific around 1943, but I can offer some examples from Umemoto's Kaigun Zero-sentai Gekitsui Sentōki where he mostly counting losses & claims from 201st, 204th and 253rd Kokutai. (Umemoto's statistics may have influenced Claringbould's narrative, as his work published after Umemoto's.) A good example would be, on July 2, 1943, a joint operation was carried out to bomb Allied installations. Umemoto described the result as one Allied Corsair lost and two more forced to land, with no Japanese losses, and concluded that the exchange was "1:0." However, IJAAF Ki-61s and Ki-43s also took part, and at least three Ki-61s failed to return. These losses were not included in Umemoto's account.
The criticism here seems to be that Ichimuru was taking Japanese claims at face value and also discounting the losses of the IJAAF. So where do his figures for IJAAF losses come from in his rebuttal? We do not know; for all we know he has just inserted US claims at face value?
However what is more telling is when you actually look at reports from July 2 1943 from the units that he has named.
There is no online record from 02 July 1943 for the 201st Kokutai available online. This is the first report available from 15 July 1943. The same can be said of the 253rd Kokutai. The other two units that are listed in the criticism did not participate in the attack.
The report from the 204th Kokutai is available and we can see that the 204th claimed 4 aircraft destroyed. This is already 4x that of what is allegedly cited in Ichimuru / Umemoto's book, and only represents one of the allegedly 3 participating IJNAF fighter units.
The fact of the matter is that the AI program he used probably translated Umemoto's book for him, and then completely messed up the units involved.
This is the report from the 251st Kokutai from the same day. There is some kind of claim in the document but the text is extremely faded / illegible. Supposedly it says that is 2 F4F's claimed with one of those being probable; even if we don't accept that...we can see that there is some form of claim in the box that is used for claims.
And here is the last relevant Japanese record from that day. This is from the 582nd Kokutai which also furnished escort for the July 2nd raid. In this report we can see claims for 4 fighters shot down.
The IJNAF claims from this raid amount to 10 US Fighters shot down. If Ichimuru / Umemoto was reporting Japanese claims at face value then his book would say that Japan had a 10:0 loss ratio on 2 July 1943, and not the 1:0 that the OP alleges. This is for an air raid in which IJAAF provided the bombers, and the IJNAF provided the fighter escort.
There is a raid on 4 July 1943 that largely follows the same formula, but was furnished escort by both IJAAF and IJNAF and in which they did take losses. His AI program has probably conflated both raids together and hallucinated events from 04 July to be taking place on 02 July in order to refute an imagined argument.
