That's great. If the London player is playing engine precision moves against someone who plays imprecise human moves then white will have an advantage.
The issue with your analysis is that you played inferior moves for black instead of playing the correct moves and then say "look how much worse black is doing".
You played the imprecise move Bg6 for black yourself and said black is doing worse instead of the correct move e5 or the most popular move at master level Ne4.
You're making assumptions about my intentions.
Bg6 is one of the top moves in that position.
Really, there are only four moves for black there: Bg6, e5, Bg4, and Ne4. A prepared London player (who likes 7. dxc5) will have responses to all 4 of these moves. It'll all be part of their repertoire.
See: Kamsky (this is how I'm familiar with these lines - from studying his games). The very first position I showed is from Kamsky (GM) vs. Gutierrez (IM):
Here we have an example where an International Master had the Black pieces against the London - and, surprisingly: they didn't have a fun time ...
Evidence that, even for an International Master, the London can pose serious problems.
Yet we have untitled amateurs on these forums acting as if the London is practically refuted ...
If you want to look at e5 instead of Bg6, here we go:
Two GMs duking it out in the World Open. Both players take turns parrying and prodding. The game ended in a draw.
My point is that the London player isn't always placid, nor does one need to always play it by rote. In the hands of an experienced player, it's an entirely valid opening choice, with more dynamic choices than some players realize.

Personally, I like to play 1.Nf3, then transpose into either: the Nimzo-Larsen, the Queen's Gambit, the Colle, or the London - depending on the defensive structure Black chooses.
I enjoy playing the London against early KID structures, as it creates a classical structure (from white) against a hypermodern structure (from Black). A fun clash of styles.
When black plays a more classical structure (pawn to d5, for example), I don't play the London, and will opt for a more hypermodern structure from white, in response ... (English, Nimzo-Larsen, or perhaps KIA) ... for similar reasons.
Every time people say this "you only look at stockfish and don't understand anything!". Not true. I'm looking at the results.
We also have to consider the purpose of the moves.
I have given my opinion that d4-c4-Nc3-Bg5 is far more ambitious and has far greater purpose behind the moves than d4-Bf4-c3-Nd2. This is reflected in the results of the games at all levels.
