You want LaTeX mode even for plain TeX files?  That's a strange wish.

TeX-PDF-mode is a minor mode and you can set its default value
e.g. with `M-x customize-variable RET TeX-PDF-mode RET'.  In contrast,
the "mode:" entry in the local variables section AUCTeX inserts is
concerned with the major mode.

"mode:" entries always toggle the mode they are referring to.  If you
activated TeX-PDF-mode per default, the "mode:" entry above will
deactivate it.
