Sounds like a typical jobsworth response ☹️.
Personally I would follow Option 1. “Call Motability a month or two before I take delivery and say that I will pay the VED (£50 a month) on the Motability car and hope that they do their admin, let DWP know, I can then get through to DWP to request a certificate, they agree (having hopefully been notified by Motability) and send us the certificate in time. ”
Maybe do this four months in advance to ensure everything is sorted 🤷. Everything is hard work, isn’t it?
