Maybe it inherits the LANG settings, but the parent should be init right.
Maybe even through the restart from your ssh shell or something?

If you start an xinet process yourself (not the service).
What will its LANG be?
Please ensure your shell doing so has the ones you want.

Like:
ensure env is good
xinetd &
check proc/<pid>/environ

If that is good, modify something and see if it inherits it all.
