Sounds like you’ve got a weird mix of route origination. Why wouldn’t you advertise to Google via BGP and have your prefix originate from your own ASN?
Big Cloud byoip doesn't generally work that way. You register the addresses in their portal and they handle everything else with the expectation that their AS is the sole origin for the prefix in question. At least that's how the AWS offering works. I presume GCP is the same. They're not acting as a general-purpose ISP.
