Is this package listed in org-latex-default-packages-alist?
If so, you might try something like:
#+BEGIN_SRC emacs-lisp
(let ((org-latex-default-packages-alist org-latex-default-packages-alist))
(setf (nth (seq-position org-latex-default-packages-alist "color"
(lambda (a b) (string= b (nth 1 a
org-latex-default-packages-alist)
'("monochrome" "color" nil))
(org-latex-export-to-pdf))
#+END_SRC
I think that would be a temporary modification just for the export.
Alternatively, you might define a new latex class like this:
(add-to-list 'org-latex-classes
'("article-monochrome"
"\\documentclass{article}
\\PassOptionsToPackage{monochrome}{color}
[DEFAULT-PACKAGES]
[PACKAGES]
[EXTRA]"
("\\section{%s}" . "\\section*{%s}")
("\\subsection{%s}" . "\\subsection*{%s}")
("\\subsubsection{%s}" . "\\subsubsection*{%s}")
("\\paragraph{%s}" . "\\paragraph*{%s}")
("\\subparagraph{%s}" . "\\subparagraph*{%s}")))
and then specify #+LATEX_CLASS: article-monochrome in the org-file.
