State Farm offering me $14,200 for my car - paid $18,500 for it 8 months ago. What can i do?

My car got totaled two weeks ago - someone ran a red light and hit me. Not my fault at all, the police report backs that up. The other driver had State Farm so I've been dealing with them directly. They just sent me their valuation and offered $14,200 for a 2021 Honda Civic with 38,000 miles on it.

I bought it 8 months ago for $18,500 and have the bill of sale. I just looked at Carmax, Facebook Marketplace, and a couple of dealership sites and similar cars are going for $17,000-$19,500. I feel like they're just making up a number. The report they sent me has "comparable vehicles" listed from a database I've never heard of and one of them is from 400 miles away in a completely different market.

Has anyone successfully disputed a total loss offer? What actually works? I don't want to hire an attorney over this but i also can't afford to just eat a $4,000+ loss when this wasn't even my fault.
