Google does have Fiber though I imagine the extent of that is still much lower than a full Telecoms company. I think the exceptional spending on lobbying comes from the sheer breadth of services that Google provides:

The filing cited privacy, data security, antitrust, taxes, tariffs, trade, the opioid crisis, artificial intelligence, cloud computing, autonomous vehicles, immigration, the future of work, encryption and national security."
