I am surprised that this works.  ox-koma-letter does the following:

#+begin_src elisp
(unless (assoc "default-koma-letter" org-latex-classes)
  (add-to-list 'org-latex-classes
               '("default-koma-letter" "\\documentclass[11pt]{scrlttr2}")))
#+end_src

and so you should be using default-koma-letter here.

Unless, of course, you have defined your own scrlttr2 org LaTeX class
somewhere (although you say you have not)?
