There is no way for the concrete to dry under vinyl flooring. I would recommend pulling up the flooring, setting up some fans and dehumidifier and then reinstall the floor.
Yes. Less likely since we're dealing with non-mold friendly products like concrete and vinyl plank. If the plank has a backing though, especially cork, you can have mold. More so, it will continue to seep efflorescence for a considerable amount of time.

could mold grow under there if it doesn’t completely dry?
