The "WARNING: ThreadSanitizer: lock-order-inversion (potential 
deadlock)" are not interesting as long as your problem is not a 
deadlock.  There's unfortunately always been quite some of those across 
the LO code base (as are also reported by Helgrind, for example), but 
they seem to rarely cause problems.
