Check out their website at pholynnsanjose.com, if you haven't already called. They offer a vegetable & tofu pho, but it's under category of beef noodle soup, so you need to ask what broth they use.
I've never asked for a vegetarian style but since vegetarian is offered in most restaurants now I have a feeling they do have at least one offering. I would assume easiest way to find out is a phone call or pay them a visit😄
