This is what I found from a Reddit comment: Debrid services literally are just like if you downloaded from the share website directly, as if you had signed up for an account with them. And/or the debrid service downloads the torrent on their server, and you stream from it.
This is already protecting you from any potential legal issue.
Some people may get warnings/potential legal trouble for torrenting directly, but this is only because when using torrent you also become a hoster of the content yourself. This doesn’t happen with these.
