I mean, this is a game of cat and mouse. YT is already very aggressive on sexual content. Content creators just find the next line and push it there.You could require everyone making videos to be wearing suits and people would still find ways to be evocative.
At some point your best move is to self moderate. Ignore those thumbnails or aggressively click "not interested" on any content like that.

No, this can't be automated. YT would need to pay staff and set a rubric. But I'm guessing that it's not financially impacting YT as is.
It could also go the other way. Add a "misinformation" label and suddenly everything is misinformation, from Jordan Peterson speeches to live recorded NASA space launches to Spongebob clips.
