No, the supported command to get \'o in math mode within LaTeX is
\acute{o} (with package amssymb). I've managed to get \'o working in
math mode with the usual set of French packages I use for LaTeX, but
it's a bad solution: the accented character is printed upright instead
of italics, LaTeX complains, and it is no more printed as soon as I
uncomment or change LaTeX packages in the document.

No, it does not: as I told in my first message (sorry for the possible
mangling with UTF-8 coding), the same error happens if you use something
like @'o inside @math.
I don't know whether the following is an acceptable solution, but
texinfo.tex could maybe turn the @math{@'o} error into a warning, as the
output produced with 'texi2pdf --batch' seems to look good. Anyway, as
we can easily reformulate the piece of LilyPond docs that causes this
error, I don't mind at all if this limitation is not fixed.
Cheers,
John
