There is no legal barrier for them to relicense Qt from LGPL to a commercial license for a customer. They are just strongarming customers into paying for licenses early on during development by refusing to do so.

Absolutely.
My company accidently used one of their GPL-only products (on screen keyboad), thinking it was LGPL. We did the right thing and reached out to them to pay for it after it was already deployed to customers.
We had to pay for the entire Qt platform. 20,000 dollars plus a per-device royalty. That was a big mistake on our part, not paying attention to the licensing.
