I assume it would have to be a prosecutor at some level in government.
Google, or any other corporation or citizen, cannot bring criminal charges... we can only file civil actions and report crimes to authorities in the appropriate jurisdiction (the police or FBI for example) who then report to prosecutors who decide whether to bring charges. Perjury is not just an offense at some specific person or organization, it's an offense to society, and society punishes through criminal prosecution (United States v. You, Commonwealth of Pennsylvania v. You, etc.).
At least that's my "Civics 101" level understanding.
