Thanks for sharing the screenshot of the error.
Your Subscription Admin / Subscription owner, seem to have enabled an Azure Policy to deny the Open AI resource creation.
Name of the Azure Policy: "ACE - Deny the creation of OpenAI resources"
You should contact your Subscription Owner and request them to disable / remove this policy inorder for you to create an Azure Open AI Resource.
You can view the policy definition from Azure Portal as shown below:

- Type Policy on the search Bar on the top.

Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
