Google records can be subpoenaed. Whether or not they are able to obtain useful information is another question, that depends largely on how much information they have to start with. Proving libel claims is general a difficult undertaking. Sounds like you have an upset neighbor who will hopefully calm down after some time passes. Should an actual claim be made, you should advise your insurance company immediately. Best wishes.
They can be subpoena'ed, but Google is not known for its cooperation, and they are known for their shark tank full of flesh eating lawyers that descend on others. Personally, I think its all bluster, and if the family in question has a lawyer in it, then that lawyer should know that opinion is not actionable. Besides, they can't subpoena Google without a court case, and they can't file a court case without a defendant.
This is general advice and does not establish an attorney-client relationship.
The internet records of Google and any other interactive web site, like social media sites, can be subpoenaed. It can be done as part of an active lawsuit that is pending somewhere or as part of a "discovery" lawsuit that is filed just for the purpose of getting the information. I don't know what was actually said by you and whether or not it meets the legal definition of libel or if this is all bluster and bullying and threats that you are hearing. Either way, you should talk to a local Libel Law attorney and not post any more info about this on the internet at all. If the person making the threats is an attorney, it is very easy for them to find your postings about this topic. You will need to talk to a local attorney who handles your kind of case. You can also search the Avvo web site under the Find a Lawyer tab, or call the Dayton Bar Association and ask for a referral to an attorney near you.
