this kind of does what you want:

#+BEGIN_SRC emacs-lisp
(require 'org-id)

(add-hook 'org-insert-heading-hook
      #'(lambda ()
          (org-entry-put (point) "UUID" (org-id-uuid))))
#+END_SRC

at least it works if you use the menu to insert a new heading. it does not
work if you type the heading by hand.
org-insert-heading-hook

you can probably write a little function that sets a uuid property.
