Currently the machinery used to generate images of inline latex
equations is used to evaluate latex code blocks. So e.g., the following
works as "expected".
#+begin_src latex :file write-fisher.pdf :results raw
\begin{equation*}
P_{i} = \frac{(2N)!}{i! (2N-i)!} p^{i}q^{2N-i}
\end{equation*}
#+end_src
#+RESULTS:
[[file:write-fisher.pdf]]
In this case it is all a matter of balancing what the majority of users
think is "expected". If specifying a particular document class is
important, than I am sure that it shouldn't be hard to update the
org-babel-execute:latex function to check for the presence of
\begin{document} and handle those cases differently (in a similar way to
how org-babel-execute:C checks for a main function).
If specifying the document class is not required your example could be
converted to the (arguably preferable) example below.
#+begin_src latex :file foo.pdf :results raw
...some text...
#+end_src
#+RESULTS:
[[file:foo.pdf]]
