The Kirin Tor only joined the Alliance AFTER the purge.
Jaina didn't get a 'get out of jail free card' because there was no reason to put her in jail. There is nothing Jaina has to answer for. The purge (although sloppily carried out during a moment of intense anger) was completely justified. Twice the Sunreavers (or, to be fair, a representative of the Sunreavers) broke the Kirin Tor neutrality, therefore they've forsaken their right to remain in Dalaran.
OBS: For people crying out saying that both the issues of breaking neutrality were perpetrated by individuals, not the whole group, it must be reminded that it is the full responsibility of the head of the group to keep their group in check. Not only twice the group failed to keep themselves in check, but also twice failed to bring the perpetrator to justice. So, yes, their removal of Dalaran was completely justified.
