Carrying a big sword all the time could reduce your agility or even your move (mitigated by mounts).
Being a flying unit could quite reasonably imply a lower base encumbrance limit... Carry too much and you can't get off the ground.
It could also be that a leader who is directly engaged in combat loses some amount of leadership bonus, since they are less able to direct the overall battle when they are busy trying to not croak.

Keeping them back out of the line of fire and/or without a weapon could be improving their leadership and dodge by a little bit at the expense of attack power.
Perhaps. The warlords we've seen carrying their own weapons are (IIRC): Jillian (who enjoys fighting for its own sake), Ansom (who wields an Arkentool, and perhaps would consider it inappropriate to put it in commoner hands), and Webinar (two occasions -- the first time, he was leading a small group and thus would immediately be on the front lines of any fight; the second time, he was going into the tunnels with the attitude that the mission was likely to go horribly wrong).
