I tried the the linked example search for "baby cat" and it returned the same three AI cats you can see in their Google search comparison screenshot on the first page. None of them labeled as AI generated.
Edit: When I explicitly choose to "Include" AI images from the toolbar option, they disappear. When I choose to "Exclude" them, they reappear. Still seems a bit buggy.
