I can't speak for piped, but I use a self-hosted Invidious instance to watch Youtube. You don't log into it with your Google account, it has its own authentication so that it can save your (distinct) subscriptions. Even if Google decided to crack down on alternate front-end usage, they can't correlate it back to your actual account.

Can't is a strong word. They might not bother, but if you're logged in to your Google account on other services from the same IP they might tie those together. Wouldn't be 100% accurate but if they decided to go nuclear ¯\_(ツ)_/¯

If this is truly frightening, you should reduce your reliance on Google since too much of your life is tied with them.
