How a particular interpretation deals with bells theorem is a fundamental aspect of understanding that interpretation - it's one of the questions any interpretation has to answer.
One interpretation which is (arguably, I suppose) locally deterministic is Many Worlds, and bell himself expressed that he didn't like many worlds as an idea very much but he did think it gave a novel solution to bells theorem.
So as far as "loopholes" in Bells theorem go, breaking the assumption that there's a single world with a single experimental result is a loophole in bells theorem that allows for a certain kind of local casualty.
