I feel like you're severely overestimating how much inspection is actually done by customs for consumer imports. I've imported dozens if not hundreds of similar products/devices that could be dangerous if you don't know what you're doing and are certainly missing any required certification and never had so much as a peep other than the occasional request for an invoice so they could charge import fees.
Also in this case if you scroll down to the spec sheet the mains voltage measurements are done with a x10 probe, meaning you'd only get ~23 volts out. Obviously that won't prevent user error from leaving the probe at x1, but at that point the device would most likely destroy itself before you can even touch it anyways.

Couple of friends got stuff from Alibaba confiscated and destroyed by customs because it wasn't marked with valid CE and RoHS marks. I'm inclined to believe that at least German customs are actively looking for electronics - they're seizing around 250k general electronics plus 250k phones each year [1].

The other scenario would be the user testing a socket and managing to connect scope GND to hot and scope input to neutral. At that point, most of that scope's "housing" aka its PCBs will be extremely dangerous to touch.
Advertising anything not actually complying with the numerous safety regulations surrounding electricity (particularly, IEC 61010-2-030) is so incredibly ignorant that it makes me question the rest of the entire product quality.
The market is littered with outright dangerous electronic devices but customs won't look into them, the volume is just too high. I stupidly clicked on an ad for an 'energy saving device' because I was curious about the scams an boy there are so many. The only one who can protect you is you yourself.
No touch protection as in it's open on four sides, right? With metal through-screws, to boot. As opposed to an enclosed, isolated case. I guess it'd be safe for low voltage measurements?
The device is only really meant for low voltage measurements to begin with, as you can see in the specifications below it's only rated for +-40V inputs. They get away with it because by using a x10 probe (which attenuates the signal 10:1) which means while you can now measure +-400V, the device itself will still only see +-40V and the software will correct the readings.
