Oh man, that was hilarious 😂 what I meant was for you to choose between “vous” or “tu” not to include BOTH!!!
I’m sorry maybe I should have explained myself better...if you are going for a more casual approach between the characters the dialogue should read as follows:
-Parles-tu français? -Oui, et toi?
-Oui, je parle français mais probablement pas aussi bien que toi.
or, if you wanted to keep the formalities:
-Parlez-vous français? -Oui, et vous? -Oui, je parles français mais probablement pas aussi bien que vous.
I’m really sorry for the confusion, honestly 😬
P. S.: as quiet as it’s been kept, Google translator is not to be trusted.
