I think the function should be written (untested):
(defun my-latex-multicolumn-filter (row backend info)
(when (org-export-derived-backend-p backend 'latex)
(while (string-match
"\\(<\\([0-9]+\\)col\\([lrc]\\)?>[[:blank:]]*\\([^&]+\\)\\)" row)
(let ((columns (string-to-number (match-string 2 row)))
(start (match-end 0))
(contents (replace-regexp-in-string "[[:blank:]]*$" ""
(match-string 4 row)))
(algn (or (match-string 3 row) "l")))
(setq row (replace-match
(format "\\multicolumn{%d}{%s}{%s}" columns algn contents)
nil t row 1))
(while (and (> columns 1) (string-match "&" row start))
(setq row (replace-match "" nil nil row))
(decf columns))))
row))
The change is setting the third argument (‘literal’) to ‘replace-match’
to t, and deleting an extra backslash in the "\\multicolumn..." string.

Unfortunately I think that’s more complicated, since it would necessitate
examining/modifying the whole table in one go, rather than operating one
row at a time.
