I think you've misinterpreted. The trial is going ahead, it's just not going to be a jury trial because the only thing the jury would be there for is to determine damages. Since Google is preemptively paying the full fine that the prosecution was asking for there'd be literally nothing for the jury to do there. It'd be a complete waste of time. The trial will instead be a bench trial, decided by a judge alone.

They weren't "getting out of" anything with this payment. The "hell" that Google was facing was exactly the fine that they paid.
