He had an Asauchi... just not in the traditional sense. White essentially substituted as one. The sealed form of Ichigo's Zanpakuto has always been that large sword he used at the start of the series. Even after losing and regaining his Shinigami powers the first time, he uses the same broken sword against Urahara. Though in all honesty, there would be very little point in Ichigo sealing his sword, all things considered.
