Something like the following should work, assuming ITEM is the item
element you have to transcode:

#+begin_src emacs-lisp
(let ((parent item) (depth 0))
  (while (and (setq parent (org-export-get-parent parent))
              (case (org-element-type parent)
                (item t)
                (plain-list (incf depth)))))
  depth)
#+end_src

> Does org-list-to-generic work in this situation?

As a good rule of thumb, it's best to rely on tools provided in ox.el.
