You can call NW award res and ask them to look at the avail of space on KL flights -- I'd be really surprised if those flights were actually sold out at this point. LP "did" get back to you to tell you that KL could not confirm the space? How long did it take, each time, for LP to check and then tell you to pick other dates? I believe that altho LP may tell us that they're submitting a long list of alternative dates/cities to KL, in fact LP is only submitting one itinerary and waiting to see if it clears/doesn't clear. That's why being armed with dates you KNOW are already avail can simplify the process. It may also be valuable to call and ask LP if they're issuing anymore KL award tickets for this year -- seem to recall that last year around this time, they were honest and telling folks that they had already used up their allotment. I'm out of country currently and can't make the call myself. Maybe they'll give you an update?!?
