Alternatively, you could just set up an alias, like:

$ alias lilypond='/…/lilypond-2.23.10/bin/lilypond'

in ~/.bashrc (or use whatever command name you wish).

Those paths look odd. /usr/local should only contain the directories
bin  etc  games  include  lib  man  sbin  share  src
and /usr/local/bin/ is typically placed at the start of your $PATH
for you by your distribution. I don't know where /usr/local/lilypond/usr/
came from, but the rest of the path, share/lilypond/2.23.10/…, does
look like something unpacked from the .tar.gz file.

You haven't diagnosed why the dates have become screwed up,
so I would assume that your tree of files is now damaged.

Rather than mess with touch, I would remove the whole tree, clean up
all the various links you made, and then unpack the .tar.gz file
again, as suggested above. Unpacking it in ~/lilypond-2.23.10/
would be fine, and an alias will save some typing.

As for lilypond-mode in emacs, I would imagine that you haven't
yet carried out the instructions in §4.2 Text editor support
in the Usage manual, so emacs can't find the mode.

If your response is that it used to work, then I would wonder
whether you used to have a distribution-supplied version of
lilypond installed, and emacs was relying on that. In other
words, it was relying on lilypond*.el files in locations like
/etc/emacs/site-start.d/ and /usr/share/emacs/site-lisp/
(or similar names), instead of those from any of the downloaded
versions you've installed/unpacked in the past.

Cheers,
David.
