There is no direct link between a chord and a trill.
A Trill (see trill.cpp) is a spanner anchored to segment, so with a start
tick and a end tick. You will find them in the _spanner map of the score.

Also as mentioned earlier, there is something for trill playback here:
https://github.com/musescore/MuseScore/blob/master/libmscore/cmd.cpp#L273
but it's not working.
