Here is what I have right now:

Adding "concentrate":"true" and "splines":"spline" to graph_attr accomplished what I was looking for. Thank you.

graph_attr = {
    "fontsize": "22.5",
    "fontcolor":"black",
    "fontname": "Sans serif",
    "layout":"dot",
    "concentrate":"true",
    "splines":"spline",
}

  blank1 = Node("", shape="plaintext", height="0.0", width="0.0")
  caddy_auth_portal - Edge(color="blue", style="bold", tailport="s", headport="n", minlen="1")- blank1
  blank1 - Edge(color="blue", style="bold", tailport="s", headport="n", minlen="1") - management_group
