Hi,
These past holidays I've been experimenting with some little useful, but
fun stuff. This is an export filter to put a decorative initial letter
in the first paragraphs of the first level sections, using the LaTeX
package lettrine (https://www.ctan.org/pkg/lettrine).

#+BIND: org-export-filter-parse-tree-functions (lettrine)
#+begin_src emacs-lisp :exports results :results none
(defun lettrine (tree backend info)
(when (org-export-derived-backend-p backend 'latex)
(org-element-map tree 'headline
(lambda (section)
(when (eq 1 (org-element-property :level section))
(let* ((contents (org-element-interpret-data (org-element-contents section)))
(lettrine-opt (org-export-get-node-property :LETTRINE_OPTIONS section t))
(contents-lettrine (with-temp-buffer
(insert contents)
(save-excursion
(goto-char (point-min))
(re-search-forward "\\(\\b.\\)\\([^\s]+\\b\\)" nil t)
(replace-match (concat "\\\\lettrine"
(if lettrine-opt (format "[%s]"
lettrine-opt) "")
"{" "\\1" "}" "{" "\\2" "}")
t nil)
(org-element-parse-buffer)))))
(apply #'org-element-set-contents
section
(list contents-lettrine)))))
info)
tree))
#+end_src
Best regards,
Juan Manuel
