I think that the AI generated tab isn't very accurate. A lot of the stuff looks hand drawn but it looks like some of it is AI. It mostly looks like just an extra added tab since most of the games don't say anything about adding any sort of AI into the content. Perhaps it could have been labeled AI by mistake too? So personally I would say that the AI generated tag for games isn't very accurate since people can easily just label it as AI even without having it.
