There’s zero things that are “dick moves” that justify the use of potentially deadly force. She could have fallen and hit her head and gotten a traumatic brain injury and blows to the chest can cause your heart to stop. The very early could have been a snuff video
He dumped the drink on her. Questionable. She had instigated the physical altercation, but this could be considered an unjustified escalation.
She lunged at him. Escalation: Assault by battery.
He shoved her away while she was attacking him; she fell over backward. Even if the beer-dumping was unjustified, he was now justified in using physical force to stop her physical attack.
She tried to stand back up; he kicked her back to the ground. Questionable. He was certainly justified in initially shoving her away, which caused her to fall to the ground; if he reasonably believed she was getting back up to continue her battery, he was justified in putting her back on the ground.
He retreated, and grabbed his things. De-escalation.
She picked up a beer bottle and threatened him with it. Escalation: Assault with a deadly weapon. (This also demonstrates the reasonableness of his belief that she would continue her battery in #5.)
He shoved her away while she was threatening him. Completely justified by her latest assault.
He retreated while she was on the ground. De-escalation.

Grabbing a drink isn’t assault. Nor is it battery. It is, at most, petty theft.
So no, he actually started the physical altercation, which means that all of your assertions are false.
