Nippon Life Insurance Company of America v. OpenAI Foundation

Issue: Whether OpenAI is civilly liable under Illinois common law for tortious interference with a settlement contract, unlicensed practice of law under 705 ILCS 205/1, and abuse of process based on ChatGPT's provision of legal advice and drafting assistance that allegedly induced a third party to breach a dismissed-with-prejudice settlement agreement.

Nippon Life Insurance Company of America filed this complaint in the Northern District of Illinois on March 4, 2026, invoking diversity jurisdiction under 28 U.S.C. § 1332. Plaintiff alleges that after user Graciela Dela Torre settled and dismissed her LTD benefits lawsuit against Nippon in January 2024, she uploaded her former attorney's correspondence to ChatGPT in January 2025; ChatGPT allegedly characterized the attorney's response as "gaslighting," advised her on how to vacate the settlement agreement, and drafted legal papers she subsequently filed to reopen the dismissed lawsuit. Nippon argues that OpenAI's intentional design of ChatGPT to provide legal services without licensure—and its knowledge, through surveillance and monitoring systems, of users' legal-assistance interactions—renders it liable as a knowing participant in the tortious interference, unlicensed law practice, and abuse of process, forcing Nippon to expend resources relitigating settled claims.

This complaint presents what appears to be a novel theory of AI developer liability premised not on defamatory output or product malfunction but on an AI system's affirmative legal counseling function—specifically, whether an AI developer can be held liable as a joint tortfeasor when its chatbot displaces licensed counsel, induces breach of a binding settlement, and facilitates improper judicial filings, potentially establishing a precedent that developer-imposed design choices enabling legal assistance constitute actionable conduct independent of any Section 230 or First Amendment shield.
