Maybe you can include the sty file as a code block that will be tangled
before export. You should put that block in a section tagged no-export.
Depending on your setup, you may need to make a code block to build your
latex file and/or pdf to make sure the tangling happens.

at the top keep this
#+LATEX_HEADER: \usepackage{filestyle}

and in the last section do this
* build :noexport:

#+begin_src text :tangle filestyle.sty
latex code for style
#+end_src

#+begin_src emacs-lisp
(org-babel-tangle)
(save-buffer)
(org-latex-export-to-pdf)
#+end_src

and finally put your cursor in the last block, and type C-c C-c. that
should do what you want.
