There's something called "font exception" which says that having
LilyPond's font in the engraving doesn't make this engraving GPL-ed.

of course not.  LilyPond is a tool; using a tool to produce something
doesn't mean that the created thing is a derivative of the tool.
Music produced using LilyPond is not a "LilyPond derivative work".

In short: don't worry.
