The kotoamatsukami crow was set to react to Itachi's eyes not his mangekyou lol. Itachi knew Sasuke would want the eternal mangekyou and that he would transplant the eyes. Now after the transplant, Sasuke wouldn't have Itachi's mangekyou eye patterns, but yet the crow would emerge and Sasuke would've gotten one shotted provided he attacked Konoha as according to Itachi himself.
