This is what AUCTeX has in latex.el:
(defun LaTeX-common-initialization ()
"Common initialization for LaTeX derived modes."
(setq-local indent-line-function #'LaTeX-indent-line)
;; Filling
(setq-local paragraph-ignore-fill-prefix t)
(setq-local fill-paragraph-function #'LaTeX-fill-paragraph)
(setq-local adaptive-fill-mode nil)
...)
Again, I can't tell why you get something else. You should investigate
with a recipe starting with "emacs -Q" and activate only AUCTeX. But
you know by now 👍
