It's no better with:

--8<---------------cut here---------------start------------->8---
  (if (and
           (not (listp (symbol-function 'org-clocking-p)))
           (org-clocking-p)
           (y-or-n-p "You are currently clocking time, clock out? "))
      (org-clock-out)
    t))
--8<---------------cut here---------------end--------------->8---

Note that I removed `fboundp' from your example, as that does load Org
immediately, if present.

Best regards,
  Seb
