json_agg method returns a json, which by default I map to any since the majority of the Typescript community prefer any over unknown. But you could change that behavior in the overrides.types.

What you want is array_agg instead:

type AnimalWithFoodName = {
  firstName: string;
  foodNames: string[];
};

export async function queryJsonAgg() {
  return await sql<AnimalWithFoodName[]>`
    SELECT
       first_name,
       (SELECT array_agg(name) FROM foods) AS food_names
    FROM
      animals
  `;
}
