Is it possible to create multiple i points in PI without using PI Builder in excel or Point Builder in PI SMT. Would it be possible to use piconfig?
Yes, it is possible to add points using PIConfig or PowerShell.
I'd highly recommend you to use the Powershell method as John Eyth. It is a purpose built tool to administer tasks like creating many tags on multiple servers.
You can find its documentation as below:
LiveLibrary - PowerShell Tools for the PI System.
I am sure above is what John wanted you to see as well. Also good resource is by Paul Martin:
Intro to PowerShell for the PI System
Also, don't forget, you can use PI System Explorer (AF SDK indirectly) to create PI Points too by embedding the PI Point configuration in AF Templates and implementing those in your AF hierarchy.
Adding PI Connectors can create PI Points automatically. If you use OPCUA server, you can enjoy this feature. (If you don't have one, it is good to remember that if you use connectors in future, PI Points will be created automatically)
