I need to run commands remotely from a PC; We have been doing so by running SSH and entering these commands.
However, with M1 devices, we are no longer in an i386 environment.
From the OSX desktop, I can configure a terminal to open in Rosetta, and the "arch" command returns 'i386'.
However, I have not been able to figure out how to have an SSH session do this.
Mac mini 2018 or later
Rosetta 2 works on a per-app basis, and does not operate as a hypervisor guest or separate operating system instance.
If you ssh into macOS, you’ll get the native macOS platform and architecture and command line, and you can then run the app as needed.
Unless the app you’re connecting to implements its own ssh server, you’re going to get the system ssh daemon. Which I’d doubt the app does.
Should you run a GUI app requiring Rosetta 2, the activation of Rosetta 2 will be transparent for most purposes; the app will appear and will launch the same as a native app.
For command-line apps, the arch command mentioned above is the means to launch an older app, pending rebuild or replacement of that app with a native app.

Ok, in that case, if you want to launch a specific i368 command in an arm environment, the arch command might be of help:
/usr/bin/arch -x86_64 <your command>
Have a look at "man arch" for the available options.
Before jumping head first into a rabbit hole, can you try to just ignore any architectural changes and try to run the tool? Does it work? If it returns an error, what does it say? A screenshot might be helpful.
The ssh connection is independent from the underlying architecture. It does not make a difference if you ssh into an intel or a m1 macOS computer as long as the used commandline tools are installed on both machines.
What exact error are you running into?
I am running a propietary executable designed and compiled to run under i386 osx.
When I am local, I have to run a "Rosetta" configured terminal window. When in this session, if I run the "arch" command the response is "i386" not "arm64".
However, when I ssh into the Mac, the response is always "arm64".
I am not a developer, nor am I familiar with OSX. I have been instructed to use a "Rosetta" terminal to run this executable, and thst I need to be in an i386 environment.
But it sounds like as long as rhe executable was compiled under i386, I can run from either command line architecture?
First follow etresoft's advice. Try it. If it works, call it a day. Because everything MrHoffman explained applies, and macOS will automatically run any intel compiled executable via Rosetta. This is baked into the operating system as a very low level.
But just to be sure. Have you tried running it via an ssh session?
Did it run or did it fail?
If it failed, what error messages did you get? Exact copy & paste text of the error messages please.
