Is there a way to include smoothing of child nodes?

Dafa

For example, for a Genesis 8 Male character, I have some jeans and I want to put a phone in the jeans pocket. I put it near the thigh and the smoothing partially kicks in, is there a way to increase the radius or - more preferably - include the phone as part of the character rather than as a separate object?

In the current implementation of Daz Studio, smoothing nodes can only have one target. You'd need to export the smoothed geometry and re-import it as a morph.

You could try using a dformer with a weight map. See the link in my sig.
