I'm sure they did as they had designed many other products before X10. They chose a capacitive supply because it cost less and had a smaller footprint. Their devices are enclosed in plastic cases so there's no shock potential. They also chose to make neutral their hot lead because they thought there was less noise near ZC (where they do their signalling) that way.

What was life like before transformers?
DC all the way. That's how Edison started out. Tesla was the one who pushed AC.
