I think Biden has done all that can reasonably be expected regarding the Khashoggi murder. As the article you linked points out, he's sanctioned more than 70 Saudi officials and cancelled an arms sale. While it's perfectly true that MBS wasn't personally hit with sanctions, the US always knew that they was never going to happen, and would have several bad outcomes if it did.
Reviewing what Biden said, no - I don't think he lied. I think he overpromised, and he certainly gave the impression during the debate that MLB himself would be punished.
