This is a shockingly high amount of FUD but little facts.
Lets start at the top shall we?
Diesel doesn't "burn" like gasoline does.
"If you toss a lit match into a puddle of diesel fuel, it'll go out."
You need to atomize it first, or heat it up a lot so it starts to "flash" or it wont "burn".
So, a firetruck with a large diesel tank is fairly safe because it takes a LOT to get it to start burning. At first all the heat is simply absorbed by the diesel slowing warming it up until it reaches its flash point.
Next, your temperatures are beyond MESSED UP.
Ignition temperature for a lithium battery is just 121 C

I have no idea where you get 2,000F (1,093C) from but this is so wrong it is embarrassing. This temperature is almost to the point Iron catches fire:

Batteries are also prone to shorts and spontaneous fires which may explain stories like this : https://www.republicworld.com/world-news/us-news/tesla-model...
There is also the "fun" reaction between Lithium and water, which firefighters often use on fires...
