VIF = 1/ (1-Ri²), where Ri² is the r-square of the focal predictor i, when regressing all other predictors on this variable.

In the outer model, the focal predictor i would be a specific manifest variable of a latent variable, and all other predictors are the other manifest variables of that predictor.
