I use STube (SmartTube) and it’s pretty good. It has ad blocking, integrated sponsorblock, various amenities, and support for casting. I think it also works without logging in.
I am not sure if it works on any Android tv or just on Amazon firestick, but the stick is its primary target. You may need to stick to the beta, as google gets more aggressive with ad blocking, it’s updated pretty often.
Don’t bother with an RPi, it will cost more troubleshooting than it’s worth (in this usecase).
This reads like the Hiss incantation
