Answer 1

You can make the field level security by metadata API. When you create the field. Also send the field level permission in Admin Profile type metadata. A sample field permission looks like below.

<?xml version="1.0" encoding="UTF-8"?>
<Profile xmlns="http://soap.sforce.com/2006/04/metadata">
  <fieldPermissions>
        <editable>true</editable>
        <field>ObjectName__c.Field__c</field>
        <readable>true</readable>
    </fieldPermissions>
</Profile>

From the Salesforce: https://developer.salesforce.com/docs/atlas.en-us.api_meta.meta/api_meta/meta_profile.htm ProfileFieldLevelSecurity represents the field level security for users assigned to a profile. In API version 30.0 and later, permissions for required fields can’t be retrieved or deployed.

As of API version 38.0, you can change field permissions to make a field editable using the Metadata API for fields that you can't change through the user interface. For example, you can deploy Asset.ProductCode as an editable field even though you can't through the user interface. https://developer.salesforce.com/docs/atlas.en-us.api_meta.meta/api_meta/meta_profile.htm
