Yes, and entities incorporated elsewhere can have assets in the US, including bank accounts. In general companies have liability in every jurisdiction in which they operate, not just where they're incorporated.
That might be true, but at that point you're fleeing the country to avoid the justice system. As a US citizen/resident, I would be very skeptical of any instructions to do that. Even as a US bank I think legal would have to look at it to see if there is liability in transferring substantial assets out of the country.
Yes, they may well be able to sneak out at night. But that's not how legitimate businesses operate, and it might change the process and outcome in the next country where litigation appears. If NSO moves and abandons assets in the US to escape liability, what happens when similar actions are brought in Germany or the UK or wherever? Presumably plaintiffs would insist on accounts being frozen immediately given NSO's absconding from the US.
Fleeing may help owners extract maximum value from the company before it collapses, but it will not serve the purposes of continuing to operate a legitimate for-profit company.
