I think it's not possible to styled ListItem because of the typescript definition of ListItemProps

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Okayyy it's really for showing the problem, the real goal is to styled the ListItem without using sx props -it will be a library component that let the user potentially use the sx props-.
