A blatant depiction of slavery is out, but the conclusion of a monster with a mind control ability named Enslave is not eliminated. Neogi favor humanoids as food more than servants. Umber Hulks are the perfect eel-spider Au Pair. In older editions, Neogi enslaved individuals through repeated doses of their venom. It gets around the 1/rest Enslave combat ability. Compulsion is going to always be icky and is usually done hamfisted.
As for Illithid being 'E' vil, they feed solely on sentient creatures. In much of the lore, they feed on the memories and emotions more than the base grey matter. You are going to have a hard time making them good, but if the Mind Flayers had negotiated a non-predatory compact inside a Wildspace System to have access to trade and resupply, they could be 'neutral'. Creepy and terrifying, but neutral. Maybe illithid would sell contracts to individuals to have full and exciting lives for a number of years before the contract comes due, then Slurp! Or ethical farming, with free-range halflings, frolicking and playing on idyllic curated worlds until the Illithid hand select 'Bobby' to be Sunday brunch.
