Have you tried the latest plugin from GitHub Action? You can add person name and their aliases in the new customize x-ray menu. You can created the ""worddumb-custom-x-ray.json" in a text editor and put it in the book folder. You could add "Livy" and see if it helps. Or add all the name variants as "Livy"'s aliases.

Example file:

[
  [
    "name a",             # entity name
    "PERSON",            # NER label
    "name-a,name-A", # aliases
    "name a desc"       # description, leave empty to use Wikipedia summary
  ],
  [
    "name b",
    "PERSON",
    "",
    ""
  ]
]

It's possible to make the plugin run in terminal and only create files, the test file already does that.
