I'd be willing to put money on the fact that if you live in the state in question, you can use your local small claims court.
EDIT - Especially given that you could argue that Google provided the service in your home state to your home address.
One option would be for her to file with a local court and seek jurisdiction. This would be time consuming and costly though. I am not sure exactly how this would work with her being in the UK.
But the courts would decide the validity of the request. A single person suing a multi-national billion dollar corporation would have a good case.
Wikipedia has some more info, including certain states that favour the plaintiff.

You can try to change the jurisdiction, but it is hard to do this for a very specific reason.
There are ways around it, and as you pointed out you can file locally and try to convince the local court that i should take jurisdiction over the case. But this would cost you money and time. Plus, you would have an uphill battle trying to convince a court to overturn a clause you agreed to in the first place.
While you cannot always do it, at least in the states, if you are negotiating a contract for your business try to get the other party to agree to dual jurisdiction. Basically stating that your local court or their local court can have jurisdiction over the contract. Some parties will agree outright, others will want it to say something like if they sue you it has to be in your court, but if you sue them it has to be in their court.
FORUM SELECTION CLAUSES ARE NOT BINDING ABSENT A SIGNED WRITTEN CONTRACT. EVEN WITH A CONTRACT, ALMOST NO COURT IN THE US WILL HONOR A FORUM SELECTION CLAUSE BETWEEN A CONSUMER AND A CORPORATION.
Think about it: if forum selection clauses did have legal effect (between consumers and corporations), you wouldn't be able to sue most companies unless you were willing to go to Delaware (where roughly 90% of naitonal US corps are headquartered). The reason we have lawsuits everywhere is precisely b/c you can file anywhere, even despite a forum selection clause.
ONLY BUSINESSES NEED TO WORRY ABOUT FORUM SELECTION CLAUSES.
Choice of law clauses are different.
Now I am by no means saying that forum-selection clauses are an end all to potential contract lawsuits (key here being contract disputes and not just any lawsuit between a plaintiff and defendent corporation). There are ways to fight the forum-selection part, but you must be prepared to fight it and pay the legal expenses involved. Sometimes it is a matter of weighing the cost versus the outcome sadly and that is why corporations end up avoiding the lawsuits in contract disputes.
And I'd probably have to sue in CA, as the other commentor points out. Most agreements do specify which districts. Or specify arbitration.
There is no legal obligation to file in the Defendant's court. US law allows a lawsuit to be filed in (1) the plaintiff's home court, (2) the defendant's home court, or (3) the home court of the jurisdiction where the events giving rise to the lawsuit took place.
Forum selection clauses ARE NOT BINDING UNLESS SIGNED IN WRITING. Most courts will not honor forum selection clauses between consumers and corporations due to the unfair bargaining power in the relationship. The other primary justification is that the corporation can afford to travel to a city where they willingly do business (i.e., provide goods or services.)
CHOICE OF LAW CLAUSES ARE BINDING. That simply means that the the court hearing the case may have to apply the law of a different state.
TALK TO A LAWYER. Don't trust random comments on an online technology discussion board, especially where those comments claim that you don't have legal rights.
