I am wondering if there is a robust estimation version of polr(),
similar to the lm() -> rlm(). If not, can anyone suggest a way to do
robust estimation with polr()?

No: What would it mean to have a long-tailed distribution of a ordered
There are ways to allow for misclassification of training data in
logistic regression, including polr, but they are very different in
flavour and implementation from robust regression.
