Fully agree with you but unfortunately that is out of any of our control. Unless you search something that is innapropriate for the AI to respond to, google and other engines with AI will always attempt to create an AI result no matter what and unfortunately it's not possible to change it. If there's ever a way to trigger "It's too innapropriate to generate a response, don't generate one" it will be added of course (if it doesn't hinder results).
I suggest you to use a search engine like Ecosia which has *optional* ai-features, allowing you to remove the AI overview stuff entirely & if you care for it, the ai search results that the extension can remove
