I don't have access to install-tl right now but it's just a script,
right?  So the first thing it can do is set the umask.  The fact that
it's called by sudo isn't relevant.

drwxr-xr-x appears on directories in /usr/local in both Mac OS and
Linux.  It would be following the normal structure.

The ONLY reason this happened is that I personally like to keep my
files restricted AND sudo inherited my preference, applying my
preferences inappropriatedly to the texlive files in /usr/local.  But
my preference to restrict access to my files is NOT appropriate for
files in /usr/local, especially files that are publically available on
the internet!
