write emacs lisp function that will transform info buffer table of contents to org-mode tree
Here's an example Emacs Lisp function that converts an Info buffer table of contents to an Org-mode tree:

    (defun info-toc-to-org-tree ()
      Convert an Info buffer table of contents to an Org-mode tree.
      (interactive)
      (let ((toc-buffer (get-buffer *info-toc*))
            (org-tree-buffer (get-buffer-create *org-tree*)))
        (with-current-buffer org-tree-buffer
          (erase-buffer)
          (if (not (buffer-live-p toc-buffer))
              (message No Info buffer table of contents found.)
            (with-current-buffer toc-buffer
              (goto-char (point-min))
              (while (not (eobp))
                (let ((level (string-to-number (match-string 1)))
                      (name (match-string 2))
                      (link (match-string 3)))
                  (insert (make-string (* level 2) ? ) name \n)))
                (forward-line))))
        (switch-to-buffer org-tree-buffer)))

To use this function, open an Info buffer and navigate to its table of contents. Then, execute the function `info-toc-to-org-tree` either by calling it from Emacs Lisp or by binding it to a keybinding. The function will create a new buffer called `*org-tree*` and insert the Org-mode tree into it. You can then copy the Org-mode tree to the clipboard and paste it into an Org-mode file.
Thank you!
