Correct.  The former is only for export, and doesn’t work with babel
features (incl. tangling)

Something like (untested):

,----
| #+begin_src emacs-lisp
|   (org-babel-goto-named-src-block "preamble")
|   (org-babel-tangle)
| #+end_src
| 
| #+name: preamble
| #+begin_src latex :tangle preamble.tex
|   % code goes here
| #+end_src
`----

You’ll need to use some combination of “:exports none” or a headline
tagged :noexport: to avoid these src blocks showing up in the exported
output.

HTH,
