Here are two ways of fixing such collisions manually:
\new Staff \relative c'' {
% Collision:
\pitchedTrill b1~\startTrillSpan d b1\stopTrillSpan
% Fixed by moving tie:
\once \override Tie #'Y-offset = #0.75
\pitchedTrill b1~\startTrillSpan d b1\stopTrillSpan
% Fixed by reshaping tie (2.16+):
\shape Tie #'((0 . 0.5) (0 . 0.75) (0 . 0.75) (0 . 0.5))
\pitchedTrill b1~\startTrillSpan d b1\stopTrillSpan
}
But it seems to me that you want an automated solution, so this probably
isn't very helpful.
