From `org-edit-footnote-reference':

--8<---------------cut here---------------start------------->8---
(add-text-properties
 0
 (progn (string-match (if inline? "\\`\\[fn:.*?:" "\\`.*?\\]") contents)
        (match-end 0))
 '(read-only "Cannot edit footnote label" front-sticky t rear-nonsticky t)
 contents)
 (when inline?
  (let ((l (length contents)))
    (add-text-properties
     (1- l) l
     '(read-only "Cannot edit past footnote reference"
  	       front-sticky nil rear-nonsticky nil)
     contents)))
--8<---------------cut here---------------end--------------->8---

The equivalent code will prevent a user from changing, deleting the
LaTeX markers, or writing past them : this is not the purpose of the
functionality.

In the same function:

(lambda ()
 (if (not inline?) (delete-region (point) (search-forward "]"))
   (delete-region (point) (search-forward ":" nil t 2))
   (delete-region (1- (point-max)) (point-max))
   (when (re-search-forward "\n[ \t]*\n" nil t)
     (user-error "Inline definitions cannot contain blank lines"))
   ;; If footnote reference belongs to a table, make sure to
   ;; remove any newline characters in order to preserve
   ;; table's structure.
   (when (org-element-lineage definition '(table-cell))
     (while (search-forward "\n" nil t) (replace-match "")))))

LaTeX fragments should not break paragraphs, or tables. So you need to
prevent inserting blank lines, or even newlines characters in the case
of tables.
