Please check out the article in case I missed anything. Assuming you need to keep your account for work, here are the direct links for each step (or instructions where a direct link is not possible):
- Go to this page and turn it off: https://www.linkedin.com/mypreferences/d/settings/data-for-ai-improvement
- Submit this form: https://www.linkedin.com/help/linkedin/ask/TS-DPRO
In addition:
- check this page for other privacy settings: https://www.linkedin.com/mypreferences/d/categories/privacy
- Delete unnecessary personal information:
Profile image>Manage>Posts and ActivityProfile image>View Profile> remove anything you don’t need to include- Go to this page and delete old resumes: https://www.linkedin.com/jobs/application-settings/



The opt out is specific to your account. If you don’t have an account, its less likely that you have information with them to delete
I guess I’ll never know, because I don’t want to have an account and I also don’t want them to have any data of mine.
I think if you don’t have an account with them, the only relevant bit is here

If a LinkedIn account shared something with your information, you can file a request about it
Thanks for the link! Done!
