Brake Fluid Leak problems of the 2019 Honda Odyssey

Driving on an expressway, the cars in front of me are slowing down, my car's collision mitigation braking system sends a visual alert with the "brake" signal coming on and I feel the brakes engaging, simultaneously I slam on the brakes, and while there was still distance between the car in front of mine and mine, I am not able to brake. The brakes seem confused, and the impact is so strong that my head almost reaches the steering wheel. The seatbelt is locked in place and leaves me sore. Once I am able to get ahold that I was just in a car accident, I am unable to lower the windows, the car is able to call for help on it's own and does so although nothing comes of that in that no help comes. Once I get off the van I notice the plate is knocked and on the floor, the bumper has fallen off and the hood and grill are curled up pictures attached. The car seems to be leaking a fluid and we are unable to start it. I believe that because we (the car and I) simultaneously having the system engaging on it's own and my slamming on the brakes prevented the brakes from working. The impact was with such velocity that it's impossible to have had them working properly. This is an important safety concern if the driver and the system are unable to work together or too confusing for the system. Interestingly, the air bags didn't deploy! additionally, the initial scan by the auto body shop had many alerts come up but the ones I would like to highlight are abs - ecm failure and integrated driver support system - brake actuator malfunction, attaching that scan too.
