Hi UnitedF1RST,
You can use rhe Revivals lounge ( as long as your lfight from LAX arrives before 1330 when Revivals closes) and then follow signs to the Heathrow Express for the 5min journey to T5 and reclear security ( free of charge).
If you are flying Upper Class you should get a pink piece of paper inviting you to use Fast track immigration
You would still need to clear secuity if you stayed airside and went via Flight Connections.
The " Clubhouse" mentioned in your post is genearally used for the lounge in the departure area of T3 ( and as you are not leaving from T3 you will not have access)
If you are not able to link your bookings, VS in LAX may still be able to tag your bags straight through to GVA.
Regards
TBS
