Do they need Biden to come out and spell it out for them or something?

No. They want Biden to get the blame. I firmly believe that is at least part of the reason you had so many governors get angry at Trump back when this all started and he said "I am going to leave it up to the states to decide what is best for their people" (which is the Constitutionally correct response obviously).

Now, if anything went wrong, it was on them. And every politician doesnt want the blame to be on them when something goes wrong. So you have seen weak governors like Hogan (who is one of the arch RINOs) trying to get the Fed involved in all of the state matters. But the Fed actually doesnt have a ton of options, and they have burned through a lot of their options getting into pissing matches with Texas and Florida.

Which, if we're being honest: go ahead! I don't care. It will only demonstrate ever more succinctly just how stupid these people are.

Especially since his little Dictator "Our patience is wearing thin!" "You will get vaxxed NOW!!" rant seems to have barely even moved the needle. At least, that is what the data starting to come in says at least. And if a "I am going to threaten your job and your livelihood!" was met with a resounding "Bet" from the American people, I dont imagine a push for shot #3 will end up much better. Especially since there are probably a lot of people like me who got the first 2 shots who will not get the 3rd.
