Seeing the info that no ai was used in all game info boxes, just because they did not use it, is odd. It is a bit like seeing a non mature warning on a non mature game. It should be the expected way, so only give information, if there is information to give, like the rest of the things in the more information box. There is also not information about how a game did not use Unity for example. Only if it did.
I agree with you, I deliberated on the wording and I may remove it. The links in the game info panel do lead back to classification pages though, so I would like to make it easy for people to discover that itch.io has a No AI section, since I feel like people are seeking out stuff like given the current discourse around gen AI content.
