A family of Microsoft word processing software products for creating web, email, and print documents.
List styles only store the settings directly associated with list formatting, such as number/bullet format, indentation around list symbols, restarts etc.
Other paragraph settings, such as line spacing, are controlled by the underlying paragraph style.
Note that the recommended approach is to set up a list style and associate a paragraph style with each level. See the article at https://shaunakelly.com/word/numbering/numbering20072010.html which uses the built-in headings as examples, although the principles apply to non-heading multilevel lists as well.
