I don't know why you think Aizen's Zanpakutõ caused Kensei's and the others hollowfication, when he wasn't even the one cutting them down. It was Kaname who used his Bankai to take them by surprise. It's possible that they were infected by some viral agent, causing the hollowfication, like how White infected Masaki by biting her shoulder; e.g. Hiyori could have passed it to Shinji, when she cut him etc.
