Yes there is, with a BIND keyword, e.g.:

  #+BIND: org-latex-classes (("article" "\\documentclass{llncs}" ("\\section{%s}" . "\\section*{%s}")))

Though you need to activate it with `org-export-allow-bind-keywords', if
only as a file local variable:

  # Local Variables:
  # org-export-allow-bind-keywords: t
  # End:

You can put the block in a :noexport: section. Then, I don't think that
you need to then :exports or :results parameters.

You can use a final filter to replace "article" with "llncs" in the
document, but there is no straightforward way, e.g., a keyword, to do
so.
