One of the things that Sanderson has pointed out in his post-AMoL question and answer sessions is that not all of Min's viewing actually meant anything significant. For example, in his Tor books #TorChat on twitter he explained:
Not everything that Min foresaw was supposed to be significant in the series, according to Jordan’s notes.
Jordan deliberately played up elements, foreseeings, and prophecies in the series that he knew were going to be minor
This means that Min's viewing could literally represent any point during the Last Battle where two men were killed by Trollocs, of which there were dozens on-screen and probably thousand off-screen. Given the vagueness and total lack of identifying details in that viewing, it's unlikely that it refers to any specific key event.
