I'm certainly no expert when it comes to this type situation. I do remember this case:

Different fact pattern, but it did involve international family court with a country that lacked ties to the US. 

I agree that a Florida lawyer could possible provide some insight.

Thank you very much! It's very true, hiring a lawyer isn't cheap.

I think it's possible in theory but in practice you'll need a FL lawyer and they will not be cheap. Maybe 

 has some thoughts about this? I'm not a lawyer, just work with them sometimes.

PS: If no one else replies, I know some FL lawyers and could call in some favors to get an opinion.

Can a person in the United States be sued from abroad?

You could try. In case of FL, see https://www.flsenate.gov/Laws/Statutes/2021/48.193
