The current libel laws are literally as good as it gets. You prove that someone is intentionally spreading deliberately false information and you can get whatever damages you can prove occurred. Burden of proof is on the accuser, there's total media freedom to report on rumors and possible outcomes, there's room for opinion pieces in the press, everything is good. "opening up libel laws" does nothing but destroy freedom of the press, because if you change "deliberately false information" to "false information," suddenly, you can be sued by anyone whenever you say "hey this is possibly a thing" and then it turns out to not be a thing.
Even if you have tons and tons of proof that something is true, so much so that any reasonable person would say that it's okay to say "yeah, that's most likely the case" you can still be sued if it turns out to be wrong. In the hands of people who will sue anyone for saying anything negative about them, that is an absolute disaster.
