To register an LLC online in the USA, follow these general steps

Choose the state where you want to form your LLC and visit the state's Secretary of State website to verify LLC naming requirements, fees, and other relevant information.

Choose a name for your LLC that complies with the state's rules and is not already in use by another business.

Fill out and file the Articles of Organization with the state. Some states allow you to file online, while others require paper forms to be mailed or delivered in person.

Obtain any necessary licenses or permits required for your LLC to operate in the state.

Consider getting an EIN (Employer Identification Number) from the IRS, which is often required for opening a business bank account or hiring employees.

Create an LLC operating agreement that outlines the structure and management of your company.

After completing the necessary steps and paying any fees, you will receive a Certificate of Organization or similar document from the state, which officially forms your LLC.

Note that the specific requirements for registering an LLC can vary by state, so be sure to research the requirements for your state of choice. Additionally, it may be helpful to consult with a lawyer or accountant for guidance on the process.
