LastPass uses Stripe for payment processing. They are a major reputable online payment vendor. You will have to find a way to use a credit card, whether it be to trust Stripe, use a prepaid card, or other method.
It is also possible to upgrade your LastPass account to Premium using the Google Play Store on an Android device or the App Store on an Apple device. You can then use other payment methods.
