This is not the intended use of tags on itch.io. Tags are the main source of visibility on itch. People search for eg “hentai”-games and see titles with this Tag. However, itch limits the amount of Tags one can add to a game and wasting one spot for something like “AI” would be punishing the visibility. Instead, itch.io has a dedicated content survey where developers are asked to tell if the game uses AI. In there this game is marked as “using AI for graphics”.
