If it is susceptible to interference from WiFi, other sources of radio waves will probably affect it too. Cellphones, microwave ovens, other displays, etc...

I'm struggling to imagine how this TV made it to production without EMI shielding. The LG response just makes it worse.

Only insofar as it is needed to prevent your device from causing interference. You're certainly free to sell something that is so susceptible to EMI that it crashes whenever someone uses their cellphone somewhere in the room (and it sounds like LG came close to this).
Putting RF shielding around the AP to prevent it from interfering with the display would kind of defeat the whole point of a Wi-Fi AP.

TFA @ Techspot wrote:According to 9to5Mac, the 27-inch version of the Ultrafine flickers when placed within two meters (6.5 feet) of a wireless router. Any closer causes the monitor to become completely unusable, and it can even freeze a connected MacBook Pro.
The publication contacted an LG support rep, who confirmed that the issue was due to the proximity of a wireless router. Writer Zac Hall was told to place his router “at least two meters away” from the monitor. LG said that only the 5K display suffered from the problem, so it seems the 21.5-inch 4K model isn’t affected.
Ars Technica notes that a key part of the monitor may not be correctly shielded from electromagnetic radiation, “and that part of the monitor is probably oscillating at a harmonic of Wi-Fi (2.4GHz or 5GHz) radiation.”
