You can create own Voiceline pack for your son.

sad son ;(

This is what ChatGPT told me about this problem:

Recommend Existing Mods: Suggest looking for existing NPC voice line mods on the Steam Workshop or other modding community websites that might have cleaner versions. They should use keywords like "clean," "vanilla," or "original" in their search to find the specific version they're looking for.

Ask for Specifics: Encourage the user to provide more specific details about what they mean by "clean." Do they want all extra features removed, or just specific content?

Contacting the Mod Author: If they can't find a clean version of the mod, they might consider reaching out to the mod's author if their contact information is available. They can ask if the author can provide a version with the desired changes.

Modifying the Mod Themselves: If they have some modding experience, they could try to modify the existing mod themselves using GMod's modding tools. However, this might be a more advanced option and should only be attempted if they are comfortable with modding.

Community Forums: Suggest checking GMod community forums, subreddits, or Discord servers where modders and players often discuss mods and may be able to provide guidance or share their own versions.
