@Dan R, you may not be getting much of a "twist" action on your kick serve because your spin rate is not high enough. Or your spin/speed ratio might be too low (your forward ball speed might be too high relative to the amount of spin imparted). You will probably find that, when you get the "twist" action/bounce on your kick serve, you are getting more of a telltale quick brush sound at impact. If you can get the ball spinning faster (relative to fwd speed), the ball should acquire enough spiral spin (Z-axis spin) as the ball travels thru the air to yield a twist bounce.
The American twist and the concept of a twist serve predates the term, kick serve, by quite a bit -- perhaps by a century. First heard the term, kick serve, used in 1990s and widely in the '00s. The American Twist usage has been around, I believe, since the 19th century.
For current usage, the twist serve appears to be one of 2 or more classifications of the broader class serves known as the kick serves. All kick serves probably have some component of a Z-axis spin (resulting in a sideways deviation at the bounce). For many kick serves, this side action is relatively minor -- the ball primarily kicks upward and forward (wrt the server) -- not very much side bounce deviation. However, for the twist serve version of the kick serve, the Z-axis component and side bounce is very pronounced. Many ppl who hit kick serves do not hit a pronounced twist version of it.

They are all kick serves, twist serve is a made up thing.
