Q: Does this model need a neutral wire? and if yes what is an alternative that is the same size but doesn't need a neutral wire?

First, you're not going to find a smart relay that doesn't require a neutral wire. It just doesn't work. Second, there's a neutral wire involved in any wiring set-up, you just have to find it. In your case, if there's no neutral wire in the switch, then that means the wiring runs breaker-fixture-switch instead of breaker-switch-fixture. You can still use one of these relays, you just need to put it in the fixture junction box instead of the switch junction box. I had to do that in my office in my house, and it works just fine. Disconnecting and reconnecting a ceiling light fixture is a little more of a hassle than doing a wall switch, but it does work.

Q: If connected to a traditional switch, how does the rocker work if you want to control manually? Does either up or down turn on and off?

Basically what it does is it’s a remote shut off switch. So if the switch is on when remotely shut off, you will have to turn off, then back on for manual use, and if off, you just flip it on then off, to turn it off

Q: Is there a way to use this switch to convert my buried in the wall, not-smart, 2 wall switch, no neutral wire, 3-way light circuit to be "smart"? How?

The switch has relays which can be controlled by MQTT plus they have an app and a public API you can communicate with if you have development skills. It does say it support Alexa and Google home but I didn't use that functionality - but I assume it links to the above-mentioned API endpoints? The Shelly website is very comprehensive, and they have a good support team so it might be worth checking with them. Otherwise, it's probably not what you're looking for. It's more a foundation for someone to build IoT devices on rather than a 'smart' switch like the kind of thing you'd find in Best Buy or a similar retail store aimed at regular consumers. It *will* switch 120v/220v loads though (check the amps and elec specs to be safe) so it could be suitable for your use case assuming the Smart Home integration can do what you need.
