2: Swords and daggers are often ok. they will have problems with specific types. Things like simple quarterstaffs are more hit-and miss. Spears are often very problematic (at least on Lexica.art). Bows are problematic if you know anything about bows (but then humans drawing them often tend to mess up as well when drawing someone actually using the bow, so not too surprising.)
I'd suspect you have the answer generally there; probably the material they've been trained on has enough decent samples of simple blades that it can spit out something decent, but it gets much more hit or miss with other weapons because the samples are less frequent and/or less good.
Things I haven't been able to get any engine to do is having a vampire actually biting someone else. Blood is questionable. and if you use an online engine, it will often refuse to draw something it thinks is "spicy".. Even if it is nothing in the description for that. And they sometimes react that way on a prompt that you have used before without problems. The free version of Chatgtp was really bad on that, and well I managed to get my account there banned. I think I figured out what it reacted to that got me banned. Never managed to get it unbanned, as the supportmails just seemed to go into the void, and no human looked at it.
That's of course an intrinsic problem; with the publically accessible ones there are going to be things that even people halfway trying to follow the law and/or ethics will have tried to block, and its going to be hit or miss how it reads those.
