To my understanding, he can only use senjutsu through a person that uses Curse Mark Transformation. So Orochimaru can use senjutsu via someone's Curse Mark Transformation, since the Curse Mark contains Orochimaru's Chakra, and also the ability to absorb Natural Energy (thanks to Jugo), which creates "Orochimaru's Sage Chakra", which is then traded with the user's Chakra for the user to utilise senjutsu. Something like that.
