This is coming from someone not very familiar with Wonder Woman's canon, so I'm curious if any of it ever shows any cases of the Lasso of Truth working without the person being tied up in the standard way? The "standard way" I've seen is the lasso around the torso, pinning their arms to their sides. Can it work by merely touching the person, or perhaps by being tied around the person in a rather non-standard way, like around the ankle, for example?
In the 2017 DCEU film Wonder Woman the person doesn’t need to be tied up but it appears to have to be tied around them to work. In the below video the first clip shows the classic bound body and arms but in the second it is just wrapped around the wrist.
In Wonder Woman Annual 1 the Lasso of Truth works by Wonder Woman, Batman and Superman just by holding onto it.
