I believe the only scene he makes a device is the one for Lois. As the player you don't need to pay for the device. He just has it done. The other scenes he has in the lab are when he's making something to aid in the capturing of specific heroines. You still need to manually purchase the device for their capture though.
Outside of heroines, for all the other characters that he "uses" a device on, he just so happens to have one on him already. I'm thinking Audrey, his henchwomen, the female villains you can post to his room, Crush, Lady Shiva, Maxima, Raven, and Talia. You don't always even hear about him using one on them until scenes later when he mentions the effects its having on them.
I image something similar will happen in Themyscira too.
