Despite the fact that Shinigami only need to come into contact with Giselle's blood to be turned into a zombie, think about how very unlikely it is that Toshiro would still be alive. I mean did you see that state he was in after Bazz-B tore him up ? Also, I severely doubt using his bankai immediately afterwards would've done him any favours. There was no indication that he was ever healed so he probably succumbed to his severe injuries soon after defeating Cang Du; at the very least, Toshiro would be in a comatose state. And even if Toshiro was still alive when Giselle found him, why would she pass up the opportunity to kill a more-or-less dead Captain ? It would be a lot more advantageous to kill him before turning him into a zombie, so that if Giselle dies Toshiro also "dies" with her since he'd already have been dead. Unless Giselle somehow turns out to be the only Sternritter who isn't genre savvy enough to do something like that...
