In this case, Alice (Google) is paying Bob (the DoJ) with the expectation that Charlie (the judge in the case) will be forced to do something in response to the payment. Bob is in court with Alice to (ostensibly) get this payment as well as a few other things. Bob and Charlie here have no relationship. Nothing about this is bribery.
If this is a bribe, then paying your parking tickets is a bribe. If this is a bribe, buying something from an electronics store with the expectation that you can download the user manual from the manufacturer's website is a bribe.
