THANK YOU @keith.sowinski
Really nice, Keith!
Changing the TypedValue with an IN[0] value instead “POLYLINE” you can use the Dynamo Objects Types Node as an input.

#if IN[0] == True:
#OUT = select_objects()
#else:
#OUT = "nothing"
By the way, the Null result is from an AutoCAD 2D Polyline (Spline). The PolylineExtensions.GetGeometry node can only handle SimplePoly Spline types.
Any thoughts how to change the Polyline Spline Cubic into SimplePoly?
