Less than 4 milliseconds. They didn’t feel a thing.
How did you get this number?

To add context here, it takes your brain somewhere around 100ms to detect and then another 250 to process pain. So 4ms is not only fast, it's absurdly fast.
To get a sense of how fast it is, go ahead and stub your toe, the time it took to feel it is 100 times longer.

Do you think they died from the water rushing in and hitting them unconscious?
They died by being crushed with enough pressure such that the air inside the sub ignited ie compressed so much it essentially exploded. Death was instant.
I know a diesel engine works off compression, but it has a fuel. All fires must have oxygen, fuel, and heat. What fuel would they have in the titan to ignite?
Water contains oxygen. With enough heat that oxygen becomes free.
"Rushing" implies something like a wave. The thing crushed flat like the plastic tube it was, and would have done so too fast to even visually track.
If you were to slowly lower an open glass into the ocean, it would gradually fill with water. So i just think its the same with the sub, albeit faster?
Sure, but "faster" here means around the speed of sound, and that's fundamentally a different thing from the playful streams we're used to. The thing was waaay down there when it went.
If there was a tiny little hole somewhere that wasn't getting larger, maybe it would slow down enough to just gradually fill the vessel. In that case, though, it would not have imploded. They found it in pieces and the US Navy heard the pop.
