You're abusing the "mode" file variable. It's intended to set the
*major* mode. See node "57.3.4.1 Specifying File Variables" in the
Emacs manual.

No. The buffer is autodetected as tex-mode buffer, and then the local
variables section is acted upon; but calling (funcall
'outline-minor-mode) does not change the major mode, so it stays in
tex-mode.
