Hi @carmenxcvii
Thank you for posting your question in the community!
What I would recommend is setting up the conditional logic against the profile property Smile State and use the condition ‘is not set.’
To set this up you would use the following logic in the show/hide function of the block.
not person|lookup:'Smile State'
This will essentially show the block when the Smile State profile property is not set.
In the future, I found this article to be an incredible helpful resource for different show/hide conditions.

I hope this helps! Please let me know if you have any other questions.
