There are non specifically defined for lmo in Scribunto, so it's just using the first available fallback, italian

https://lmo.wikipedia.org/w/api.php?action=query&meta=siteinfo&siprop=namespaces

"828": {
    "id": 828,
    "case": "first-letter",
    "subpages": "",
    "canonical": "Module",
    "*": "M\u00f2dul"
},
"829": {
    "id": 829,
    "case": "first-letter",
    "subpages": "",
    "canonical": "Module talk",
    "*": "Discusi\u00f2un dal M\u00f2dul"
},

As noted in another ticket

This task is a follow-up to T244394. Please mention such context - thanks! :)

Ok, the correct translation in Lombard for "Module" is "Mòdul"

You can translate all Scribunto messages to Lombard yourself over at the Scribunto message group at https://translatewiki.net. The message you probably want to change is Nstab-module.

No it’s not.

You also can’t translate special words and namespaces on translatewiki atm

Oh sorry, my fault, I misread the comment on the translation. And also forgot that you can't translate namespaces on translatewiki.net.
