Mike Challis answered:

You can edit your theme to fix it.

or you can edit the css in the form advanced options to add font styling.

How to change the color or font styling for the input titles on the contact form:
Go to the contact form settings page, click on Advanced Options, look
for the setting “CSS style for form input titles on the contact form:”.
edit as needed.

good luck!
