Then maybe put that in game description.
Also I'm not the one asking for money either. :3
Well, it's in the tags. And in my opinion if you can't tell the difference you should not care. Stable diffusion is a tool and most artists use or will use AI with adobe/photoshop without declaring it at all (they are just better at covering up mistakes)
The game is free and I'm asking for money for my time spent for development, not just the art. Creating a game like this is not a 1-weekend-and-I'm-done thing.
