So I have been thinking is there a Leica out there like the Leica O but with a capping shutter, slow shutter speeds down to 1 sec, no finder, just an accessory shoe, and a good collapsible 50mm lens that can be had for a reasonable price, ie a couple hundred dollars.
There are no Leicas out there which are that reasonable in price, with the exception of the less-collectible I and II model screw-mount Leicas, which do not have speeds down to 1 second (that would make them III models). The addition of a collapsible lens would probably push you over your price point in any case.
I want to have a small, compact, quiet camera that I can load with Tri-X and carry with every where and know as long as I do my bit, I will get a good photograph.
Quiet can be achieved by use of a leaf shutter instead of a focal plane shutter. Additionally, leaf shutters generally allow flash sync at any speed. Few go to 1/1000 of a second, though, generally topping out at 1/500.
This camera does not even need to be a Leica, it could be a FSU LTM camera, which I really know absolutely nothing about.
You could easily obtain a Zorki or a FED LTM camera with collapsible lens for the price point you're looking for. Quality tends to vary, so budget a CLA at the minimum.
With respect to the Bessa T, the Bessa L is smaller yet (no rangefinder). Same trouble with collapsible lens, though, I presume.
I would second ZeissFan's recommendation regarding the Kodak Retina series, as well as the excellent (one of my personal favorites) the Agfa Karat IV:

The Karat IV came with one of a variety of lenses, I am very fond of the f/2 Solagon. The lens doesn't collapse as much as the entire front of the camera does.
Minus the rangefinder, I like the size, weight, construction quality, lens, and extreme quietness of the Zeiss Ikon Contina. Available with 45mm 3.5 or 2.8 lenses, avoid the 'Pantar' replaceable front element versions.
I suppose I should not say this, but just FYI, I have found in my search for cameras similar to what you are describing, once one gets into the aspect of 'small' and 'folding', one must also consider 120 rollfilm folders in 6x4.5 or 6x6 - some of them were quite small, hardly bigger than some folding 35mms. And the difference in quality based on negative size...oh my.
