Lilypond itself doesn't have (La)TeX as a dependency -- see:
http://lilypond.org/doc/v2.12/Documentation/user/lilypond-program/Requirements#Requirements

However, the lilypond-data package in Ubuntu lists several TeX-related
dependencies/pre-dependencies, as you can see by typing

  aptitude show lilypond-data

at the command line:

Can anyone explain why these dependencies should exist (unless it's just
that Debian/Ubuntu people have got things wrong)?

Best wishes,
