Do I have to remove it all?
Storm knocked out approx 25 foot from top of 40 year old/80 foot dawn redwood. Do I need/have to remove the whole thing?

I'm sorry that your beautiful tree was damaged. Trees can survive for many years after being topped like this, the recommendation is that if over 50% of the crown is lost, the whole tree needs to come out. https://mdc.mo.gov/sites/default/files/downloads/TreeCareAfterStorms.pdf
