#1 - " none of whom admit any liability to the undersigned but all expressly deny any liability"
it is my understanding that the policy holder and State Farm have accepted full liability
#2 - " This release expressly reserves all rights of the parties released to pursue their legal remedies,
if any, against the undersigned, their heirs, executors, agents and assigns."
so I am supposed to give up my right for further legal remedies but the liable party is not?
Both of these are very standard clauses in settlements. If you don't like them, the short answer is that you will likely need to hire an attorney to sue to win a definitive judgment...but there is always the risk that you lose.
You can negotiate the terms, but will find that you will get a big pushback. I think you are misunderstanding number 2. Number 2 makes it clear that the "parties" which means both you and the other driver/insurance agency are unable to pursue any legal claims in the future.
As for who is "liable" as long as they pay for your damages, it will mean little in the long run that the paper says no one was liable.
