Wow that's some good art!!
Since you can run faster than the librarians I found that running the whole time was the best strategy (which isn't necessarily a bad thing, it beats waiting for the librarians to walk past you)
I ran into one situation where one of the family members got stuck up against a wall and would just move back and forth. It's probably a navmesh quirk if I had to guess
Another time while I was running around two librarians randomly got stunned? I'm not sure if that was because of those boards on the ground.
