[MCU] How did Spiderman not get arrested?

Peter Parker is a superpowered individual that has not be regulated by the government at all. The accords are in full play at the time of homecoming. Besides talks from iron man of keeping low. Should he be in prison, he's not in the avengers he's working for nobody.

You've misunderstood the Accords.

It's not "any and all Superpowered people doing anything heroic must be controlled by the UN."

It's Avengers and others operating at that level. Additionally Inhumans are required to give some information to Shield.

So Spidey hasn't been arrested for breaching the Accords because he hasn't.
