Often it picks, and it rarely signs alone. Typically the general counsel or chief legal officer holds the budget and the final call, and legal ops runs the evaluation and recommends. AI is where that varies most.
The Thomson Reuters Institute heard two patterns from legal ops leaders in 2026. "Some ops leaders reported that they are generally empowered to make AI purchasing and operational decisions, as long as they're accountable to the GC's office. Others say their department's AI use is closely tied to that of the larger business, and the overall legal department assumes procurement and operational concerns." In the second pattern the company's AI program, IT and procurement typically sit in the room, and a pitch built only for legal stalls.
So ask early: who signs, does legal AI go through a company-wide AI review, and which enterprise AI tool will you be compared with? If legal ops is your champion rather than your buyer, give it what it needs to carry the case to the general counsel and to IT. In-house, legal ops often knows the rest of the buying committee better than anyone, so ask it to draw the map.
Example (invented): a 25-lawyer department wants an AI contract review tool. Legal ops scopes it and runs the pilot, the company's AI council reviews data handling, IT checks single sign-on and the GC signs. Legal ops signed nothing, and nothing moved without it.
