I definitely don't consider myself a guru, but I had a similar problem. I
built a function that finds and removes the empty line and then added this
via add-hook to org-export-latex-final-hook. I suspect one of the real
gurus can suggest a better way to do this, but this works for me.

Here's my code that you can adapt as necessary.

--8<---------------cut here---------------start------------->8---
(defun remove-line-from-exam.tex ()

(if (search-forward-regexp "\\documentclass\[[0-9]+pt]{exam}" nil t nil)
    (while (re-search-forward "\\\\question\n\n" nil t)
      (replace-match "\\\\question\n"))))
      
(add-hook 'org-export-latex-final-hook (function remove-line-from-exam.tex))
--8<---------------cut here---------------end--------------->8---
