Dear @danielerametta
"Do you know if there is a plugin compatible with Laytheme that does this?"
I personally have not tested multiple accounts with Lay Theme & Woocommerce, I am unsure but these links may help you:
( Discusses Stripe Connect, Stripe Payment Gateway plugin & PayPal Adaptive Payments )
https://wordpress.org/support/topic/splitting-money-from-woocommerce-into-2-accounts/
https://ignitewoo.com/woocommerce-extensions-plugins-themes/woocommerce-paypal-adaptive-payments/
( Discusses how PayPal Adaptive payments is not in use anymore & PayPal Payouts is a similar though not exact option )
https://docs.woocommerce.com/document/paypal-adaptive-payments/
https://www.paypal.com/merchantapps/appcenter/makepayments/payouts
(NOTE: Says as disclosure "Payouts to Venmo are available in US only.")

I Think Stripe connect may require you to add code into the Theme though not positive. This is the most promising thing i have found:

Lay Theme supports the use of some Shortcodes :
