This website has piracy sites that works in almost any tv web browser: https://www.bestfreestreaming.org/ These work in web browser included into tvs like samsung. For android tv browsers i have found that https://heartive.pages.dev/ works the best. Internet archive also works in android tv browsers. I have not tried it in the browsers thats included into tvs tho
To get around geo blocks use https://cobalt.tools/ and go settings privacy and toggel on always tunnel files
