LibreTube - uses Piped as video source by default. Subscriptions and playlists can be created, all without actually interacting with YouTube.
Clipious - uses Invidious as the video source. Also allows for subscribing and accounts. Lesser known client
NewPipe - Gets the source directly from YT. Allows for subscribing and creating playlists
Additionally, there’s also ReVanced that lets you patch the regular YT app to include useful features.

I imagine you’re exaggerating but if not then I’d say that’s a tad extreme. That being said, their official setup guide does provide steps on how to install it but I think if I didn’t have prior experience with some of the software it mentions I think I’d struggle so maybe a different guide by someone else is better?
However these obviously require having something that this can be run on, like a VPS, which aren’t free, so that is another barrier for entry to consider.

No, which I mentioned in my comment.
