The United States has no prior speech restrictions, only limitations on the use of finite public spaces (town squares, broadcast spectrum), and restrictions based in the illegal origin of certain materials (CSAM). Libel laws are not restraints on speech, they're an avenue for torts arising from harms proven after they occurred. Specifically, the restraints the US does not have are called prior restraints. There are no banned media outlets or silenced individuals, which would be prior (before the fact) restraints on speech.
