If you add org-redisplay-inline-images to org-babel-after-execute-hook,
that should happen whether or not the #+{BEGIN,END}_LaTeX lines are
there (you can get rid of them by using :results raw).

This works for me (after I C-c C-c on the second source block):

--8<---------------cut here---------------start------------->8---

* foo

#+begin_src latex :file frac.png :results raw
\(
\frac{1}{2}
\)
#+end_src


* bar

#+BEGIN_SRC elisp
(add-hook 'org-babel-after-execute-hook (function org-redisplay-inline-images))
#+END_SRC
--8<---------------cut here---------------end--------------->8---

That however may be saying that there is a problem with your setup. Is
there anything in *Messages* that indicates a problem? Assuming that
debug-on-error is not set currently, you might also want to

M-x toggle-debug-on-error RET

and rerun the code block to see if there is some error that is triggered
(sometimes errors are caught using condition-case and are hard to see).

Just to be clear, the frac.png (I renamed it to avoid clobbering an unrelated
test.png file in my setup) *is* produced in my case.
