Pretty much the title. Chemically speaking what’s going on when this happens?

No chemistry, just physics.
Burning oil is lighter than water and hot enough to flash-boil it.

When you pour water into burning oil, it has just enough time to sink into the oil before turning to steam. Steam takes up 1700 times as much space, meaning if you poured in a liter of water, you will get a violent steam explosion as the water suddenly decides to take up almost 2 cubic meters of space. And since it sank into the oil beforehand, it’s aggressive conquest of your kitchen throws burning oil everywhere.
