Itch hasn't removed Stripe as a payment method, so you should be able to use it if it's a game that charges for Itch.
The problem is that Itch has a mode (chosen by the person selling the game) called "direct to you," where the game developer is responsible for charging for the game. In this mode, the developer can choose whether they want PayPal only or Stripe as well.
Most likely, you won't be able to buy that game through Stripe because of the game's creator's decision, not because Itch is removing card payments.
