Is there a tool that would allow lines to be automatically drawn around objects such as Buildings, Roads CLs, Road Edges in Pix4DMapper.

I think you may have to update to Pix4Dmatic/Survey to vectorize.

Yes, as mike10 mentioned PIX4Dsurvey can automate some of this. It has line detection for road CLs and edges (white lines on the edge of a road). You will still have to digitize buildings.
