How do I start with an LLM for coding? On Linux specifically?

I'm quite experienced, been coding since the very late 1900's, but I've been ignoring this

What LLMs should I use? I'm happy to pay a little for a good one

What text editor? I'm usually a vim user, but I guess I have to change.

So I can let the LLM have write access to the code? How is that safe and secure?

Can I give it instructions via voice input?

I want to do something dumb at first like: "set up a git repo for a python project. Please include the usual linting and static analyst tools, like type checking. We're going to implement a 'cashu mint'. Please implement a basic web server with the basic endpoints required in the mandatory NUTs. Start with just stub implementations of the endpoints, we can fill in the correct implementation together later"

Is that the kind of instruction that I can give?
