I don't know what that measns.
VPN = Virtual Private Network
It's used by some people (such as companies with their employees) to set up a secure network such that remote employees can validate that they are within the network when they use company-approved applications that occur "within the company firewall".
It can also be used to obfuscate your personal computer IP address and network by routing yourself through an intermediary (the VPN), which many people use for some nefarious purposes like pirating movies/etc, such that anyone who tries to figure out who is on the other end of a computer connection will see the VPN's IP address, not the actual user's.
Your IP address
typically also associates to your general location, so if you connect to a website it can use your IP address to try to determine your location. For example, Windows has a weather app in the taskbar. When I'm not connected to my work VPN, it believes I'm in Mission Viejo. When I connect to my work VPN, it assigns me an IP address within the company domain and advertises an IP address based upon company HQ, and thus it suddenly thinks I'm in San Jose, CA and displays the weather there.
If you had some sort of VPN or something else advertising an LA-based IP address from your home laptop when you go to Google's website, they think you're in LA. So if you pull up Maps, it'll default to a location in the LA area.
But if you don't know what a VPN is, you're almost assuredly not using one. So I don't know why Google thinks you're in LA.
