It would be up to the courts if you've done anything wrong though - downloading a torrent file isn't illegal, per TFA. Who's to say you followed through with a torrent client to use it?

If you get sued, you've suffered damages and you have a cause of action. You'd need to show that YTS wrongly provided your information, but in the hypothetical where you in fact did nothing wrong, that seems theoretically doable.
You might have a malicious prosecution case against the party that sued you. I still don't see a cause of action or damages against a third party that provided information that they likely would have been forced to provide in discovery anyway.
