We are working on POC to integrate our appliaction with Okta for MFA. In the process of doing same, we are finding ways to integrate Oracle database with Okta as a IDP. But I can see only LDAP/AD as IDP in free version of developer account. Do we have any option to integrate Oracle as IDP, if yes please let me know how can I achieve this.

You might be looking in the wrong place. If you want to add Oracle as an IDP the instructions for this are here: https://developer.okta.com/docs/guides/add-an-external-idp/saml2/before-you-begin/
There are instructions there for using social identity providers but also OIDC and SAML 2.0. I think Oracle can do SAML 2.0, yes?
OKTA support a lot of Identity Providers as mentioned below & apart from these OKTA may support IDP through generic OpenID Connect or SAML.
Oracle RDBMS is still not in the list of supported IDP.
