Would it make sense to provide a script,

create-texlive-directory-at-default-location.sh,

which would attempt to create a writable /usr/local/texlive,
if that fails prompt the user

/usr/local/texlive does not exist and can't be created (rerun as sudo to create)
/usr/local/texlive exists but is not writable/executable (rerun as sudo to modify access rights)
/usr/local/texlive exists and is writable/executable, sub-directory 2019 created (you can proceed with ./install-tl)

In first two cases the sudo run would create the /usr/local/texlive then handover the access rights from root to the user, although I am not versed enough into those matters to know if the sudo executed script can recover the own:grp of the non-sudo user who issued sudo

Best,

Jean-François
