How different "be forced to do something" and "leave someone no choice"?
In this context there would be no difference between the two. When you "leave someone choice" but to do something, it generally means that they are forced to do something, usually against their will. When you are "forced to do something" it means you are made to do something with no possibility of choice. As you can see from these definitions the two phrases are essentially synonyms of each other. Ex: Dan is forced to remove an item from his cart. Ex: Dan has no choice but to remove an item from his cart.
