Hi Matt,

If I may, I think org-ql can help you here.  It should also work much
faster than org-map-entries, because it can skip to entries with the
desired to-do keywords (although you could also use the MATCH argument
to org-map-entries to improve its speed).  Try this function (untested):

#+BEGIN_SRC elisp
(cl-defun org-lms-return-all-assignments-ql (&optional (send-all nil) (also-mail nil) (post-to-lms t))
  "By default mail all subtrees 'READY' to student recipients, unless SEND-ALL is non-nil.
In that case, send all marked 'READY' or 'TODO'."
  (interactive)
  (message "Mailing all READY subtrees to students")
  (let ((todo-keywords (if send-all
                           '("READY" "TODO")
                         '("READY"))))
    (org-ql-select (current-buffer)
      `(todo ,@todo-keywords)
      :action `(ol-send-just-one ,also-mail ,post-to-lms))))
#+END_SRC
