I think a suit could be possible. I think there are a couple of cases out there that have used identity theft laws to prosecute folks running revenge porn sites (among the phrases I never dreamed would enter my lexicon). The harm here seems comparable. Google "identity theft" and "revenge porn" and "lawsuit" you should get some useful articles. I think the cases were in California and/or Florida. They were based on state law and I don't know what comparable laws exist in Louisiana, but ultimately your options depend on whether the person that did this has any money (can't get blood from a stone) and the cost to litigate. Your girlfriend may have a libel/defamation case as well.
