EOP license for on premises users in a full hybrid
I think you don't need to. According to article https://docs.microsoft.com/en-us/exchange/hybrid-deployment/move-mailboxes#what-do-you-need-to-know-before-you-begin
The Microsoft 365 or Office 365 Exchange license must be assigned only after the migration is complete. You then have 30 days to assign the license.
I think the license is for the Exchange Online mailboxes only once it is migrated. For the mail flow going in-and-out of your on-premise Exchange Server, HCW (Hybrid Configuration Wizard) automatically creates an inbound and outbound connector in Exchange Online Admin Center for your Exchange Server.
Also this might help:
For general overview of Exchange Hybrid, you can refer to https://docs.microsoft.com/en-us/exchange/exchange-hybrid.
For prerequisites of Exchange Hybrid, you can refer to https://docs.microsoft.com/en-us/exchange/hybrid-deployment-prerequisites.
For mail flow, you can look into https://docs.microsoft.com/en-us/exchange/transport-routing.

Hello,
thanks for your answer.
My doubt is that in the article https://docs.microsoft.com/it-it/exchange/transport-routing it is said:
Route incoming Internet messages through the Exchange Online organization
The following steps and diagrams illustrate the inbound message path that occur in your hybrid deployment if you decide to point your MX record to the EOP service in the Microsoft 365 or Office 365 organization. The message path differs depending on whether you choose to enable centralized mail transport.
Important
You may need to purchase EOP licenses for each on-premises mailbox that receives messages that are first delivered to EOP and then routed through the Exchange Online organization. Contact your Microsoft reseller for more information.
