I had thought the 'means to lockout' were to be permanent re>110.25, but it appeasr the osha doc differs?

Correct for when NEC requires a lockable disconnecting means.
About only time NEC gets involved with lockable disconnecting means is situations where the disconnecting means is not within sight of the equipment it serves, yet NEC doesn't have a general rule for all remote disconnecting means to be lockable - just specific situations.
LOTO safety programs want things locked off in all instances, even if it means using temporary locking means, and usually doesn't matter if the disconnect is within sight or not.
The within sight disconnect NEC requires for motors- doesn't need to be lockable. Your safety program will want you to lock it if you use that to disconnect power to work on that motor or it's driven load though.
