High-quality search engine without LLM-generated results?

I'm looking for a search engine that prioritises or only returns results from high-quality/trusted sites and no AI generated slop.

Especially for medical questions it's a frustration to wade through AI-generated crap.

If such an engine doesn't exist, I'm keen to talk about how one would build such a search engine.

Or is the only solution to limit your searches to specific sites you trust?
