It all comes down to balance. They don't kill the Vasto Lords for the same reason they don't just invade Hueco Mundo to do a mass extermination of the hollows. Yes, the shinigami are equipped to destroy the current Vasto Lords and adjuchas with ease. But if they go crazy doing that, there'll be too many souls in Soul Society. Soul Society is already a terrible place to live for many, but it'd become even worse if it becomes even more overpopulated than it already is.
What happens when it becomes overpopulated? Mayuri has to then do the morally grey job of working over time to exterminate all the excess souls. And then assuming those souls get reincarnated into the real world, that would mess with the traffic of Souls that the Soul King has to manage, which would probably then lead to opening up a whole new can of worms. In the worst case scenarios, I could see the Soul King simply exterminating the excess souls from existence to bring the balance back though.
Actually, spelling this out just made me come up with a new theory. Yhwach referred to the Soul King as his father. What if the Soul King initially created the Quincy bloodline for this very purpose. What if there was a point in time when there was too great of an imbalance and the Quincy's were the Soul Kings long term answer to help manage this? Anyways, just food for thought.
