@Riot: How do I read my account data?

So I requested my account data and have some questions as to how to read it.

So it comes with all these JSON files (I know how to read JSON Objects)

My question is on the chatLogs and the groupedReports files.

In groupedReports are these verified reports? As in Riot thinks these are valid? Or are these overall reports counting bogus ones?

For the Chat logs these seem really random. Like useless. I get what "sendto" "All" means but what about "ORDER" and "CHAOS"?
