I am trying to set up family sharing. I don't have a credit card and I use a debit card for my iTunes which isn't accepted.
Is there any other way I can prove I am the consenting adult to allow family sharing?

Not if you want to create child accounts, a credit card is required by law : Family Sharing and Apple IDs for kids - Apple Support
Before you begin, make sure that you're using a credit card as your iTunes Store and App Store payment method. To comply with child online privacy protection laws, you will use the CVV or security code from a valid credit card as part of providing your parental consent. If the card on file is a debit card or another payment method, you’ll be asked to provide a credit card before you can continue. After you create the child's Apple ID, you can change your payment method back to a debit card.
