I don't think you need a separate tort - filing a false DMCA claim is already actionable. I think it carries 3x damages too. However, very few youtubers understand that they have strong legal remedies against false DMCA claims, and they can file counter-notifications fairly easily too (these undo the effects of the DMCA claim).
I believe they are DMCA claims. The exist because it grants youtube imunity in the process. Youtube had no incentive to get involved except for pissing off their content creators. If you can't counter claim/sue then get loud. Let your viewers know.
Edit: reading in another thread that perhaps this is content ID. Not that, that is any better.
