They would have a very good case against the government if that were to happen. I suspect that the supply chain risk designation will not last long (if it goes into effect).
Some vendors will decide to sue the government. Others may decide that switching to another LLM supplier is cheaper and lower risk.
And I'm not sure your confidence in how the courts will rule is justified. Learning Resources Inc v Trump (the IEEPA tariffs case) proves the SCOTUS conservatives – or at least a large enough subset of them to join with the liberals to produce a majority – are willing sometimes to push back on Trump. Yet there are plenty of other cases in which they've let him have his way. Are you sure you know how they'll judge this case?
