Presuming an investment advisor pitching themselves as providing some kind of standalone, non-brokerage-affiliated "AI Investment-bot-as-a-Service" platform, the "bots" could be being operated in the name of their clients, acting upon said clients' brokerage accounts, with full explicit consent. (Like how Mint operated in its clients' names upon their online banking accounts, with full explicit consent.)

Ironically, I believe Robin Hood themselves offered a similar "AI Investment-bot-as-a-Service" system; though theirs was a much more mundane design, legally, in that it operated upon the clients' accounts within the Robin Hood brokerage, rather than upon the clients' accounts in external brokerages.
