@thobenjo You can hide tool bar / command bar options using JSON formatting for all users, see view-commandbar-formatting. Unfortunately, JSON formatting cannot read user groups & group permissions so you cannot target it for particular users.
Consider below approaches:
- If normal users should not be able to create list items, grant only "Read" access to them on this list - it will remove few of the tool bar options
- Create a new site page, add List web part on the page and select your list to show. You can then hide the tool bar from list web part settings. Also, you can hide see all link from SharePoint list web part so that user will not navigate to original list page.
