The democrats submitted this legislation into the Senate in September:

Which doesn't surprise me at all. The Democrats opposed the OBBB. They think the government should reverse many of those policy provisions. Individual Democrats - perhaps even large groups of them - will introduce bills trying to undo it. They did it before the shutdown, and they'll probably do it again after the shutdown. In fact, many Congressbeings - of both parties - have bills they introduce every single Congress to undo something they dislike.

That doesn't mean, though, that the Democrats have ever made passage of that bill - or anything in it other than the ACA subsidies - a condition of passing the CR.

While I have no doubt that the Democrats (like the GOP) have a wish list of all the things they'd like changed, I don't think that bill is Chuck Schumer's list of negotiating points on the CR.
