IANAL but I'm guessing that having a designer with credentials might
help with certification (or it might not -- the # I heard for UL was
~US$8K so I abandoned that idea and have no experience), but I doubt it
has anything to do with protecting yourself against liability. If
people want to zap themselves and sue you, they always can, at least in
the US (whether they have a case doesn't matter until you get to court,
as I understand it). I think you'd want to talk to an insurance company
for that (unless you're assuming the pro designers would have their own
insurance, but if they did they'd pass the cost on to you anyway).
Just guessing here...
This is another reason why it might be better to offer these as kits. It
eliminates some of the liability risk and the need to have them eval'd by
the various regulatory bodies, both in the US and elsewhere. A third party
could always offer to assemble kits for others for a nominal amount.
