If variable is exogenous,we don't need to `ordered`,is that right?
I cannot control testee's choice, then I think likert scale data is exogenous,is that right?

I'm not sure I understand your question. Any variable that is part of your model, is endogenous. An exogenous variable is one outside the model (e.g. gender). This has nothing to do with Likert or if you are able to control the item responses. In your example you have an example question q12. I assume this is an item in your model (endogenous, dependent variable) which is influenced by the latent trait.
The reason for declaring variables ordered is to make sure they are not treated as continuous variables and that the polychoric correlation matrix is used for the calculations.
