Chris Franklin will be able to diagnose it correctly first time; will the OPC guarantee that if they change the LCA it will cure the creak?
100%
I'll put money on it being worn DU bushes in the front Bilsteins - Chris diagnosed and sorted this on my car a few years ago now. Suggest you don't waste money with OPC's, spend it with suspension and chassis specialists like Centre Gravity. I can't remember what I paid for Chris to sort the issue, but I'm pretty sure it was under 1k for both front dampers refurb and proper geo set up
