I have a question about the billing and the shipping address

I have a non US LLC and have my permanent Canadian address at seller central but no virtual US address.

Do you know if I should give this seller central address to supplier which is my Canadian address?

And what has to be the amazon address?

Thank you

Are you trying to ship inventory to Amazon?

You need to create a shipment plan and amazon will provide you with the address and that address you can provide to the supplier.
