What do you mean that Google is a tier 1 ISP? Do they provide transit to anyone?
Interestingly, if you can advertise a sub-block and override the bigger block's advertisement, what's stopping people from just stealing sub-blocks from ISPs?

The thief has to either be upstream of your connection, or peered at an extremely high level with others trusting their BGP advertisements. There was a hilarious incident not that long ago where the Pakistanis accidentally blackholed YouTube's IP-block globally (instead of just within the country).
