Of course, you can initiate Assistant from the lock screen by saying the OK Google/Hey Google command or pressing the dedicated Assistant button. But Assistant has no permission to access contacts, calendars, reminders, email, photos, etc., without unlocking the phone. For example, to make phone calls, first, you need to unlock the phone.
