How to change font style for Description, Response and other fields?

My research shows that old version of Google forms allowed to set different font styles for EACH type of field (question Title, Description, Response etc.).

It used to be possible to switch to the old version of Google Forms and do it, but it is currently disabled - all new forms are created under new UI.

The woman changes font to Decorative, but the only thing changed are question titles.

My question: how to achieve that font change in all fields, not just the title? By any means, can be complicated workaround.
