I suggest (org-export-with-backend 'latex headline contents info) to not
depend on the actual name of the translator.

There's no :toc-title property in the communication channel. The
exhaustive list of its properties is written in ox.el, at "The
Communication Channel" section.

Because you're not using the proper tool. If you just want to modify the
string returned by the `latex' back-end, use a filter. You will have
access to the transcoded headline (in LaTeX format, as a string) and the
communication channel.
#+begin_src emacs-lisp
(defun fb/my-headline-transformation (headline backend info)
(when (eq backend 'latex)
;; Here HEADLINE is the output from `latex' back-end, as a string.
...
))
(add-to-list 'org-export-filter-headline-functions
'fb/my-headline-transformation)
#+end_src
What I suggest gives you access to the headline as parsed data. This is
much more powerful, but a completely different task.

There are already many ways to alter output from a back-end. It's just
a matter of using the right tool.
