Can we build a zero-inflated ordered probit model in Mplus? If not, would a ZINB model be a close approximation?

Are you thinking about more than 2 outcome categories? Is the outcome ordinal?

Yes, 5 ordered categories

Zero-inflated modeling is equivalent to a two-class model with all zeros in one of the two classes. You can use zero-inflated ordered probit by introducing a latent class variable C(2) for each variable that has a zero inflated distribution.
