You could pass expect_title as an option?

>>> import json
>>> import guessit
>>> print(
...     json.dumps(
...         guessit.guessit(
...             'The.Red.Line.S01E01.HDTV.x264-KILLERS.mkv',
...             options={'expected_title': ['The Red Line']}
...         ),
...         indent=4
...     )
... )
{
    "title": "The Red Line",
    "season": 1,
    "episode": 1,
    "source": "HDTV",
    "video_codec": "H.264",
    "release_group": "KILLERS",
    "container": "mkv",
    "mimetype": "video/x-matroska",
    "type": "episode"
}

guessit The.Red.Line.S01E01.HDTV.x264-KILLERS.mkv -T "The Red Line"

GuessIt found: {
    "title": "The Red Line",
    "season": 1,
    "episode": 1,
    "source": "HDTV",
    "video_codec": "H.264",
    "release_group": "KILLERS",
    "container": "mkv",
    "mimetype": "video/x-matroska",
    "type": "episode"
}
