It would be better to start with /usr/local/texlive. Remember, it is
not possible to upgrade TeX Live 2025 to 2026, you have to install it
but installation of 2026 will use your settings from 2025. In order to
do it as a normal user, /use/local/texlive itself should be owned by
that user but /usr and /usr/local shoul be owned by root.

It's the advice from the documentation.
