If we're going to remove old libLLVM at all, I don't think we
particularly need to be selective. If we remove any libLLVM then
there's risk of breaking a few packages that might be installed
until pkg_add -u is done, though nothing really critical. vlc is
the one that's most popular. And it's by far the largest in
/usr/lib (~90MB) so I think the helpfulness in terms of avoiding
too much growth in /usr outweighs the downside.

So this is what I'd probably choose..
