Sure, brass should be fine, looks like that's what is on your red RO/DI line saddle clamp anyway. You might ask about nylon compression fittings too. They may be in a different aisle but shouldn't be too far from the other plumbing stuff. The only other thing that comes to mind is 'john guest' fittings?
If you have the clearance at the cold water shut off, you're best bet may be to go with the 'vampire' saddle clamp fitting. You'll still want a shut off valve for the RO/DI though. No getting around that.
