By avoiding it.
They are what they are. They are exemplars. Their lives are for us to emulate, or at least try to. Instead of saying we should trust them, I would just say we should learn from them how to trust God.. What better example of this than the Blessed Virgin?
Some, like Aquinas, are among the world’s great thinkers. We can learn about the world well from him, if we choose to. Others, like Aquinas and Augustine, are great theologians. We can learn a great deal about Scripture from them, if we choose. We can ask for their intercession. All the Saints bring glory to the faithful and the Church.
All I was saying is that I reserve trust for Christ and the magesterial teachings of His Church. There is no reason NOT to trust that the saints, as I said, are exemplars. My answer to the OP was only in the sense of theology and their private revelations. We are not bound to agree with every single word of every single saint. But I do trust that they are wise exemplars who can assist us on our journey toward holiness. Why would that cause an issue?
