This isn't possible on Youtube right now. The automatic tools for detecting LLM-generated content have far too many false positives. And obviously no one is going to pay an army of people to curate the content. The best thing right now is to rely on the reputation of individual channels that you are personally familiar with.

Youtube's automatically applied label will be worse than useless unless they've made some remarkable breakthrough, which I doubt. They'd be better off just using creator-applied labels, and of course if they would label anything that Youtube itself contaminated with automatic translations or its ilk, that would be good too.

I'm not particularly religious but I did give up Twitter for lent as a test of my self control.

I highly recommend everyone occasionally do this with social media as it was somewhat eyeopening how much better I felt overall. This was mostly due to not being exposed to the doom scrolling you can eventually get pulled into (despite efforts not to).

I did miss feeling like I was "plugged in" to the stream of news/memes etc though.

YMMV but def recommend.

A nicer way that also works on mobile is turning the watch history off. C

Yeah exactly, they could have made their service useful by showing your subscriptions instead. Yet, they decided to enshittify for people who want choices.
