The RIAA is specifically making the allegation that "the source code was designed and is marketed for the purpose of circumventing YouTube’s technological measures to enable unauthorized access to our member’s copyrighted works" [1], justified by the references to copyrighted works in the youtube-dl readme and source code. If it wasn't for that, it'd be much easier to argue that it's designed for non-infringing purposes only (or one of the other exceptions to the DMCA's TPM clauses), like you could plausibly argue for libdvdcss.
