I was definitely wondering this. As I understand it they make money on order flow and don't charge for transactions (is that right?). But allowing LLMs to trade dilutes the true information in the order flow.

On the other hand maybe it's just chasing trends, like their previous forays into blockchains. It pays because it keeps their name in the news.

Robinhood (and retail in general) order flow is valuable precisely because there's already no information in it. It's assumed to be more or less random.

Institutional order flow can move the market, or be an indicator that the market is going to move in that direction. So executing against it a worse bet than executing against retail flow.
