When you generate the final output (jpeg or tiff) from RAW with

Tina is right, the original is unaltered. You are right, the changes
made in LR are saved in the output. They are also saved by LR as a
'recipe', so next time the Raw file is opened, it will look as it was
when last open.
All the noise about non-destructive editing is meaningless when working
from Raw files. No one writes back into the original Raw format. It's
not possible, as the Raw formats don't have the capability to store
alterations to the Raw data. So - NO - converter/editor destructively
edits Raw files.
For me an untouched output image is the JPEG embedded inside the RAW
or the JPEG directly from the camera when you shoot RAW+JPEG.
I've never looked at it that way. There are lots of camera settings that
change the JPEG outputs. You don't change any of them, so that's the
"untouched" output? I would say it is "touched" by the preferences of
the maker.
Canon's DPP, Oly's Viewer and SilkyPix for Panny all do a pretty good
job of reproducing the appearance of their JPEGs. Viewer seems to be
particularly good at this. Not a surprise, as I assume they use the same
calculations as used by the firmware to make JPEGs.
However, I've never liked their results as well as ACR's defaults.
Adobe, of course, aims to make Raw conversion from all cameras look much
the same. As it happens, I like their preferences better than those of
the manufacturers whose cameras I've used, but I can imagine others
disliking them. DxO Pro's defaults make Oly and Panny images look pretty
bad to my taste. It has some things that work better than ACR or my
plug-ins, but then I have to adjust color, contrast, tonalities, etc.
far more than with ACR.
I have gone so far as to process for distortion, noise and/or,
aberrations, output TIFF, load TIFF and Raw into PS, then use Match
Color to make the image look much closer to my preferences. Then, from a
base I understand, I can make further adjustments.
