In today's world, if Meta did release full source they used to create Llama, there are only about a dozen institutions that have the capacity to actually do anything with that, and no one has that kind of spare capacity just lying around. So the question of having the source for now in this case is less about being able to do something with it, and more about behind able to examine what's going into it. Aside from making it so it won't tell me how to make cocaine or bombs, what other directives has it been programmed with on top of the intial training run. That's what's important here, so I disagree that is a red herring. Both aspects are important here, but the most important one is to not let Mark Zuckerberg co-opt the term Open Source when it's only model available, and definitely not even actually Open at that.
