They're not denying anything about programs other than ACR. That's telling. They didn't say "your TV doesn't listen" or "your TV doesn't collect"

"Everything" would include the microphone, both in the remote and the TV. They're claiming to split off the audio, with one path going to the speakers (and there to your ears), and the other path being hashed (and from there to LG).

They still claim to get your media's audio, but deny using the microphones.

They explicitly state that the audio ACR is done through the "TV’s internal audio processor". e.g. rendered audio, not recorded audio. I mean, you could stretch the claim to have it internal include recorded audio, but that seems dubious.
