SPOILER..
It's was never confirmed Jinx is dead.
As the bomb explode, there's a trail of Jinx's pink shimmer trail, heading towards the air duct.
Plus, Caitlyn investigate the HexTech building and saw an air duct, suspecting Jinx escaped through it.
The last scene of Arcane show air-ship flying above the ocean, it was the kind of air-ship that Jinx said she would ride one day, back in S1.
and the Series end with "THE END" written in Jinx's style.
