It wasn't "inevitable", it took Red Hat and some other key players addressing the concerns the businesses and governments had, which took the better part of a decade. If LLMs as an ecosystem don't implode in the next year or so I imagine you'll start to see some big consultancies starting that same process for them.

Red Hat? I don't think they are involved in the moves to FOSS for government agencies, mostly because they're American, and the ones who are currently moving quickly (in the government world at least) are the ones who aren't American and what to get rid of their reliance on American infrastructure and software.
