That's not how internet connection protocols work.
If the client is connected to the server, and the client crashes, your operating system only knows how to pop up a report that it broke. It doesn't know what the client was sending at the time, or how to re-open that connection and continue sending data that you have crashed.
From Riot's servers' perspective, it's the same as if you turned off your computer. Bugsplat is a sepparate program that is not connected to the servers and only monitors the client as a background task. Even if a bugsplat window DOES show up, you have to tell it to send in the report for any data to be sent to their bugsplat server (NOT the client queue server, mind you). Even if your wifi disconnects or crashes and you get a prompt about pvp.net disconnection, FROM THE SERVER PERSPECTIVE you have gone dark and are no longer connected to the queue.
It doesn't matter if your computer knows what's going on. If a client severs connections via a crash or otherwise (and loses connected to peers in queue) then there is no way for the servers to know what happened. The default response when someone suddenly disconnects is to close the queue, because 99% of the time it's someone who turned off their client to jump queue.
