I was thinking about something like this (untested):

--8<---------------cut here---------------start------------->8---
(let (template)
  (defun ngz-set-template (new)
    (setq template new))
  (defun ngz-latex-process (file)
    (case template
      (a (do-something-with file))
      (b (do-something-else-with file))
      (otherwise (do-default-with file)))))

(defun ngz-latex-class-to-template (info backend)
  (when (org-export-derived-backend-p backend 'latex)
    (ngz-set-template
     (let ((value (plist-get info :latex-class)))
       (cond ((string= value "classA") 'a)
             ((string= value "classB") 'b)
             (t nil))))
    info))

(add-to-list 'org-export-filter-options-functions
             'ngz-latex-class-to-template)

(setq org-latex-pdf-process #'ngz-latex-process)
--8<---------------cut here---------------end--------------->8---

Obviously, you need to activate lexical binding.

I was talking about BIND keyword, not about your initial implementation.

I think the problem comes from `org-todo-keywords-1'. Its value is
probably not updated during export.
