Don't even bother applying. Every university in the UK requires students with at least 12 9s at GCSE, 5A* predicted, and more extracurriculars than events at the Olympics!
You have excellent GCSE grades and predicted A level grades! Looking at the page for the 3 year LLB, the typical offer is AAA, which is lower than your predicted grades, so you certainly have a chance. If it's any reassurance, I got an offer from Birmingham (not in Law) a few days ago and my GCSE grades are *only* 445677888 (:
