Hi,

I have read the docstring of `org-latex-toc-command' too literally
to discover that specifying anything else than "toc:nil" works.

The attached patch contains a proposal for improvement.

Below there is a not so small mwe.

--- begin mwe ---
#+title: Table of Contents Test
#+latex_class: article
#+options: author:nil date:nil toc:1
#+latex_header: \usepackage{listings}
#+latex_header: \usepackage{minted}
* Test ~toc:~ and ~org-latex-toc-command~
Anything else than ~toc:nil~ in ~#+options:~ above exports the TOC.
#+caption: Execute this block before exporting to a LaTeX buffer or 
file.
#+begin_src emacs-lisp :results silent
   (when (require 'ox-latex nil 'noerror)
     (setq-local org-latex-src-block-backend 'listings)
     (setq-local org-latex-toc-command
      (cond
       ((eq org-latex-src-block-backend 'verbatim)
        "\\tableofcontents\n\\vspace{10pt}\n")
       ((eq org-latex-src-block-backend 'listings)
        "\\tableofcontents\n\\lstlistoflistings\n\\vspace{10pt}\n")
       ((memq org-latex-src-block-backend '(minted engraved))
        "\\tableofcontents\n\\listoflistings\n\\vspace{10pt}\n"))))
#+end_src
--- end mwe ---
