A triggered ability is a type of ongoing ability that is delayed until a specific scenario or game action takes place. When the given situation occurs, a triggered ability activates, and can be tied to either an instant or ongoing effect.
...
While triggered abilities are triggered by a condition or situation happening, they may not insert themselves between other abilities to resolve. Instead, they are pending until all other abilities resolve, and then the triggered event may activate.

With that in mind, a ML that is in battle is interrupted by 2KH; all triggers are 'ongoing' effects, and since it was played in battle, it would be interrupted.  While interrupted, it is temporarily undone, and thus cannot be active.  Regardless of any other effects, you cannot activate his ability based on the draw of 2KH or anything else that occurs during the interruption.  Those things happened when it wasn't active, and before it later reactivates (as per the definition of interrupt); it cannot trigger off of any draws or searches happening in-between.

Now, what if ML is in territory, or in the case of Gifts?

The phrase “interrupt the battle” includes interrupting the following:
● all active ongoing abilities
● abilities that are defeating one of the characters you control in battle
● the last card played in current battle if it was played by your opponent.
Interrupt the battle only includes such abilities if they were activated on cards in the current battle.

Those ongoing effects in territory are not interrupted.  However remember that, as underlined above from Triggered Abilities, these triggered abilities are pending until all other effects resolve.

If there are pending abilities when an end the battle ​ability occurs, the pending abilities never take effect.

Since they are pending abilities that are waiting for other effects to resolve, and End the Battle causes any pending abilities to "never take effect" (as we have moved to another phase), those triggers that are still pending cannot activate (they 'fizzle').  If you use 2KH and then play an End the Battle, there is no search from ML nor draw from Gifts, because those were triggered by the draw but pending, and the remaining effects ended the battle before they could complete.

TL;DR: ItB does interrupt a ML in battle, and it cannot "see" cards being drawn while interrupted because it is not active.  ML or Gifts cannot search or draw if the battle ends before they can complete, as they were pending.

Somehow I managed to overlook that bolded section and was the cause for my confusion. Thanks.
