> Assuming Apple itself doesn't bypass Little Snitch, I don't even think Apple is doing the level of telemetry Microsoft does.

Little snitch doesn't talk directly to the kernel's netfilter/iptables/nftables framework so some traffic may be hidden from it (low-level stuff that cannot be accessed via the API). I don't use it so I don't know if there is a way to bypass this in the settings or with special permission.

You could always route your Mac through a device you can then monitor traffic on and get a ballpark. I don't see why Apple would do so much telemetry and go through so much effort to hide it though.
