This is because "_" chars are usually protected from conversion in
links, but the LaTeX exporter might be confused by links it doesn't
know. 

What about this :

(org-add-link-type
   "citet" 'ebib
   (lambda (path desc format)
     (cond
      ((eq format 'latex)
       (if (and desc)
             (org-export-latex-protect-string 
	      (format "\\citet[%s]{%s}" desc path))
	 (org-export-latex-protect-string 
	  (format "\\citet{%s}" path)))))))

Check for other uses of `org-export-latex-protect-string' in
org-latex.el to better understand in what contexts this function 
is useful.

HTH,
