I can point you to several projects that have been done over the years that are not covered by your blog.
Please do! LVT's are indeed an area I've only looked at superficially. I'd love to hear/read about projects that have explored this angle more in-depth. I'm aware of one person running a print shop in the US who built his own machine for exposing the film negatives; the name evades me at the moment, but perhaps you know who I mean. I think he also prints color carbon or otherwise maybe dye transfer. I know I've read a brief description of the machine he built which included some photos, but no critical details on control systems etc.
Regarding image setting negatives - they are quite popular with the colour carbon crowd as the dot pattern holds highlight detail better than con tone inkjet negatives ( I think because there is nothing to hold onto when processed out in hot water) - this is the reason I went to gum process as hot water is not needed and I feel the highlights hold much better.

100W COB UV LED lights people like Calvin use with the 60-degree lens it's sold with
it looks like he also has the light source a fair distance from his mask
In theory if you had well collimated light and a fine enough resolution to do half-tone masks then light uniformity doesn't matter at all, as long as you expose at least long enough that the dimmest area is fully exposed.
My own quick tests of printing a dithered image went poorly
