Most of my current battojutsu (My sensei was a student of Nakamura Sensei's for 40 years) curriculum consists of all standing techniques. And from what I've read on the subject of Toyama Battojutsu, it's almost entirely all standing. We do have some seated waza with the shoto/wakizashi, though.
From my limited experience and research, the koryu iaido arts all contain mostly kata that start from seiza (note: "limited" being a key word here).
