Looks good, I'd say.

Are you sure that AUCTeX is really loaded?  If it is, then the output of
C-h f latex-mode RET is:

,----[ C-h f latex-mode RET ]
| latex-mode is an alias for `TeX-latex-mode' in `tex-site.el'.
| 
| (latex-mode)
| 
| Major mode in AUCTeX for editing LaTeX files.
| See info under AUCTeX for full documentation.
| 
| [...]
`----

If AUCTeX is not loaded, then the standard emacs latex-mode (that
doesn't define/use LaTeX-mode-hook) is used producing this output:

,----[ C-h f latex-mode RET (in emacs -Q)]
| latex-mode is an interactive compiled Lisp function in `tex-mode.el'.
| 
| (latex-mode)
| 
| Parent mode: `tex-mode'.
