No it wouldn't. Metal counts, not marketing. So the only AA services that gets EC261 cover are those departing from Europe. No AA services to Europe are covered, and that includes anyone on a 125 ticket and/or marketing under a BA flight number. The Regulations talk about the "operating carrier" throughout, which takes away any leeway relating to ticketing, marketing or codeshare.
