I would like to export the Nordlink power cable relation to GeoJSON.

Until now I'm using the API with python-overpass and the following query:

relation(5500685);(._;>;);out geom;

As output I'm getting the LineString two times (!) plus all points. Example:

{
  "geometry": {
    "coordinates": [
      6.5962545,
      58.181566
    ],
    "type": "Point"
  },

While when using the Overpass API manually (Link)

[out:json][timeout:300];
(
relation(5500685);
);
out body;
>;
out skel qt;

I only get the LineString:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {
        "@id": "way/370147304",
        "@relations": [
          {
            "role": "",
            "rel": 5500685,
            "reltags": {
              "type": "collection",
              "wikidata": "Q1961296",
              "wikipedia": "no:NordLink"
            }
          }
        ]
      },
      "geometry": {
        "type": "LineString",
        "coordinates": [
          [
            6.6807119,
            58.2607599
          ],
          [
            6.694153,
            58.2131834
          ],
          [
            6.6534177,
            58.1893486
          ],
          [
            6.5962545,
            58.181566
          ],
          [
            6.4788896,
            58.1497393
          ],
          [
            6.4419395,
            58.0867718
          ],
          [
            8.4853879,
            54.2985972
          ],
          [
            8.7676507,
            54.179769
          ]
        ]
      },
      "id": "way/370147304"
    }
  ]
}

How can I get the same result (without points) like the manual query by using the API?

The two queries you mention here are different, so it's logical that you'd get different results. Have you tried simply using the same query?

Note that Overpass-API doesn't output geojson, it outputs a json representation of the osm node/way/relation data model. Overpass Turbo has some code that converts the osm data model to geojson.

How to convert this json representation to plain geojson?
