Does the wireless box need line of sight?

Yes. The Zero Connect box should sit within sight of the screen's receiver, ideally below or in front of it. Walls, glass and people in the path can interrupt the signal.

Is the M3 better than the LG G3?

They share the same MLA OLED panel and picture quality. The M3 adds wireless connectivity and a cleaner install; the G3 is wired and usually the better value if cables are not a problem.

What refresh rate does it support?

The panel runs at 120 Hz and supports VRR, so it handles 4K/120 Hz from PS5, Xbox Series X and PCs. The wireless link carries that full signal.

How many HDMI ports does it have?

The Zero Connect box provides HDMI 2.1 inputs for consoles and receivers, plus USB, Ethernet and antenna connections. Port count varies slightly by region.

Does it support Alexa and Siri?

Yes. Alexa works through the TV and Siri through AirPlay 2 and HomeKit. Google Assistant is also available on WebOS in most regions.

Is the 83-inch version worth it over the 77-inch?

The 83-inch gives a noticeably bigger image for large rooms and the same panel technology. Pick it if viewing distance is over about 10 feet; otherwise the 77-inch is easier to place.
