I have no idea if the USA has a debtors jail or not, but I don't think this is about going to jail for being in debt, it is about going to jail for breaking a court imposed order.
The court order could have been about a restraining order, in which case you go to jail for breaking a restraining order. This does not mean that the USA has a jail specifically for any possible violation of a court imposed order.
The US doesn't have debtor's prison per se. Only certain kinds of obligations, which are already associated with "jailable" offenses can result in something that looks a lot like debtor's prison. In some cases not being able to pay a debt really should carry a jail sentence, for example in case of clearly fraudulent behavior.
John Oliver talks about a particular kind of "debtor's jail" in a recent episode of "Last Week Tonight". It seems though that appeal courts don't look favorably on such jail terms.
