She's actually accused of fraud, for (allegedly) lying to US companies that what they were doing would not be in violation of any US embargo. The legal theory here is that when she made materially untrue statements that caused US organizations to commit a crime she committed the crime. In broader terms, any financial interaction in dollars likely goes through a US financial institution of some kind, who will be legally obligated to carry out all US embargo rules. There are ways around this, but they are, at present weird hacks that you have to go out of your way to do.
