I don't really understand the link between kanou and the clowns. but I don't think they had done enough search to know that Kaneki wants to have a date with Rize. They shouldn't consider him as important, they couldn't have been sure he would date her, or be with her when she trap him, and had the time to investigate on him. So there's not many solutions : They see rize hurting a human and they didn't know his blood type, so it was an improvisation and Kaneki wasn't important. maybe just a human was fine.

In all the case, for me, a mysterious ghoul like rize shouldn't let many information about her in her way(like her blood type).

Then, even itori didn't know the true identity/name of this woman(maybe a lie but I don't really think she lie to Kaneki about that).

So for me, kanou and the clowns didn't know about her blood type. the surgery wasn't based on the blood type ( and we know the blood isn't the only factor for the sucess of the operation ).
