A quick scrape of the two sites gives (literally a diff of sets of the strings used in language selection),

In Kagi, not Google:

  Crimean Tatar
  Santali

In Google, not Kagi:

  Crimean Tatar (Cyrillic)
  Crimean Tatar (Latin)
  French (Canada)
  Inuktut (Latin)
  Inuktut (Syllabics)
  Santali (Latin)
  Santali (Ol Chiki)
  Tshiluba

They really must have copied Google, because like I said this was diffing exact strings, meaning that slight variations of how the languages are presented don't exist.
