Hey mate!
I concur! My left hand is also sacred to my playing!
As righties, we could get by with just our left hand! shit, I'd create some kind of mouth strumming contraption if I ever found my self without my beloved right hand!!!
Touch wood, I'll never have the need to invent such a thing!

I think the chords are (standard tuning)

G13b11sus2 G 13th Flat 11th Suspended 2nd
and
A5add#5add#9 A 5th Add Sharp 5th Add Sharp 9th

I use site which is great man - jguitar

Bloody hell chief! I play some random long named chords like that, but very rarely research their correct musical name!

stay safe mate and look after those chord creating left hand digits!
