You cannot steal anything with that set.

You need to set eject settings in the config if you don't want them entering it. That's what the setting is for, and it will also prevent them from doing damage.

"Eject Enemies From Purchased PVE Raids": false,
"Eject Enemies From Purchased PVP Raids": false,
"Eject Enemies From Locked PVE Raids": false,
"Eject Enemies From Locked PVP Raids": false,

Lock Raid To Buyer And Friends sets them as the owner, and allows only them to loot. That's it.
