This seems like a very reasonable way to handle it.
Edit: Disclosure: I'm not an American.
The only thing keeping them in check is the courts, and that practically operates in geologic timeframes compared to the rate they are breaking laws.

There are years of precedent and common practice that makes police and police like entities basically unreachable by law. Between qualified immunity, presumption of regularity and generally all the roadblock and convoluted technical rules supreme court placed between possible judgement and police ... courts can do only so much.
Should they try to put security staff in harms way attempting to resist ICE entry?
ICE are thugs doing illegal things, but I also think that these things are for the courts to resolve, not something that should be handled with physical force.
The only other policy I can really think to have is to call the local police and tell them that ICE are executing an illegal search and hope.
So not citizens’ houses but one where someone is in the country illegally with a final order of removal.
And these guys aren't the police.
The minimum follow-up actions I'd expect would be filing a police report, sending all-staff emails reminding people to be on the lookout for tailgaters, and reviewing security at reception.
If there was a specific risk of ongoing intrusion attempts, then I'd also expect legal action (eg. injunctions or restraining orders) to be taken in mitigation.
It's perfectly reasonable for staff to want to seek assurance that those sort of basic measures to ensure their safety are underway.
After the killing of Pretti (execution is probably the more correct word), I guess even some US staff can not be so sure about what would happen to them.

There is, actually, a lot that Google can do here, in terms of making itself a hard target.
