I disagree that it has anything to do with Latin America, or any other foreign denomination, since it shows in the browser as plain Google in English.
If you had it in your logs as a referer, it seems logical that a user came from there. Very interesting. Might be a new way for Google to spread user searches around on different data centers?
English is the default language because:
1) Geotargeting your IP
2) Latin America has different languages, Portuguese, Spanish, etc...
The Google domain of Argentine (www.google.com.ar), Brazil (www.google.com.br) and others has CNAME www.l.google.com as DNS alias.
