I believe it is illegal in all States. A windshield protects the driver and provides clearer vision.
I would recommend you have them come to you. They will replace the broken windshield at your home or work place.
No, it is not illegal to sell a car with a cracked windshield in the state of Illinois. However, it is illegal to drive a car with a cracked windshield in almost any state.
