Hi Ray,
Have you done any search at all? I did a search on "R package ROC latent
variable" and got several hits.
In particular the package randomLCA seems relevant
https://cran.r-project.org/web/packages/randomLCA/vignettes/randomLCA-package.pdf
I glanced at the documentation which mentions 2 other R packages that also
seem to address your needs - poLCA and BayesLCA.
HTH,
Eric
