I think one possibility would be using a parse tree export filter:
#+BIND: org-export-filter-parse-tree-functions (katex-verbatim)
#+begin_src emacs-lisp :exports results :results none
(defun katex-verbatim (tree backend info)
(when (org-export-derived-backend-p backend 'latex)
(org-element-map tree 'special-block
(lambda (block)
(when (equal "katex" (org-element-property :type block))
(let ((cont (org-element-interpret-data (org-element-contents
block)))
(create-export-snippet ;; idea from Nicolas Goaziou
(lambda (v)
(org-element-create 'export-snippet (list :back-end
"latex" :value v)))))
(apply #'org-element-set-contents
block
(list (funcall create-export-snippet cont))))))
info)
tree))
#+end_src
#+begin_katex
E = -J \sum_{i=1}^N s_i s_{i+1}
#+end_katex
==>
\begin{katex}
E = -J \sum_{i=1}^N s_i s_{i+1}
\end{katex}
