Is there a sensible way to remove website from google search?

depends who owns it. your own site: verify it in search console and use the removals tool for a quick hide (lasts about six months), and for permanent either noindex the pages or return 404 or 410 and google drops them within a few weeks. don't block it in robots.txt, that stops google ever seeing the noindex. someone else's site: you can't remove the site, you can only ask google to remove specific results that break its policies, personal info, explicit content, copyright, that sort of thing. there's a form for each.
