Yes, Genesys Cloud for Salesforce integration supports Salesforce Person Accounts.

Genesys Cloud for Salesforce integration treats the Person Account as a Name attribute, which corresponds to the WhoId of the Salesforce Task record. The integration allows the Related To attribute, which corresponds to the WhatId in Salesforce, to be used for other purposes. This manipulation allows you to associate a call log with both the Person Account and other Salesforce objects including, cases or custom objects.
