I have to include the following rhetorical appeals but idk if this is ok and i'm stuck on including ethos...
Ethos: trustworthiness or credibility
Logos: logic, data
Pathos: emotion

Here's my sentence:
Maddy persuades her parents to buy her an iPhone for the purpose of accountability—to access educational tools, to call parents if there is an emergency, and to call first responders if a family member dies.
I think you've covered all three here. Credibility is covered by the argument that she could us the phone to access educational materials and to call her parents in case of emergency. Trustworthiness is also implied in both. The emergency arguments both also involve pathos.
You've covered logic here, too, with all three arguments.
To include ethos in your sentence, you can focus on establishing Maddy's trustworthiness or credibility. Here's a revision of your sentence that incorporates ethos:
Maddy, an exceptional student who consistently delivers outstanding academic performance and demonstrates responsible decision-making, persuades her parents to buy her an iPhone for the purpose of accountability. This allows her to access essential educational tools, ensuring she can maximize her learning opportunities, as well as providing a means to promptly notify her parents of any emergencies and even contact first responders in the unfortunate event of a family member's passing.
By highlighting Maddy's exceptional qualities, such as her academic performance and responsible behavior, you establish her credibility and trustworthiness. This appeals to ethos because it helps persuade others by showing that Maddy is a reliable individual who can be trusted with an iPhone.
