Using a debrid service is paying for a third party to do the torrenting, so your IP is not in the torrent swarm. Your ISP knows you're using the service, but they don't know whether you're streaming illegal content, which means there are no grounds to subpoena neither the ISP nor the debrid service logs.

a VPN is probably not needed imho.
