Keep in mind that classical CDs don't sell nearly as well as pop to begin with, so the lack of demand would turn off the major record companies regardless of a perceived lack of demand for the format. Then add to that the fact that, due to the expense, many of those "major" labels are backing away from recording orchestras anyway, resulting in a number of the orchestras creating their own labels. They really don't have the funds to do a limited vinyl pressing, many of them are struggling to just keep playing. Finally, remember that most recordings of orchestral performances these days are made with digital recorders. Why put a digital signal, already compromised vis a vis an analog tape master, through a conversion process to make it analog? Seems to me the worst of both worlds, the shortcomings of a digital recording added to the weaknesses of vinyl cutting, pressing and playback, and an electronic conversion in the middle of it to boot. You might find a few labels that would do something like this if they can get funding (Water Lily, for example, which records in analog and did a project with the Philadelphia Orchestra, or Mapleshade), but nothing like it on a broad scale.
I think Steelhead's suggestion is best, get used vinyl of performances/orchestras/pieces you've never heard, it's like a new recording by one of today's orchestras.
