It is highly likely that you will face legal action if you do not change the name of your website.
Pastebin already has a presence at Pastebin.com, holds a US trademark, and is recognized by the World Intellectual Property Organization. Do you believe that using Pastebin.ai will be permissible? This might be a possibility if your site offered different services than Pastebin.com, but it doesn’t. Given that your site replicates the services of Pastebin.com, they have a strong basis for legal action. Additionally, they are represented by proficient attorneys, as evidenced by their association with Cislo & Thomas LLP. https://cisloandthomas.com/
If I could easily discover your version of Pastebin.com that only differs in its user interface, it won't be long before Pastebin.com itself notices.
If you keep "Pastebin.ai"... Well I wish you luck lol. You have 🖲️🖲️🖲️'s on you that's for sure.
