Offering Jobs to Soon-to-Be Grads: How to Handle Contingent Offers and Uncertainties?

The company I work for would like to send an offer to a college student who is graduating in August 2023, with the disclaimer that if anything changes, either party can withdraw from the agreement. I am suggesting sending a letter indicating that if a position is available at the time of graduation and all background checks are satisfactory, an offer will be made at that time. What are your thoughts?

You can make an agreement now, making it obligatory for him to join. I am not sure how the legal system works in the USA and whether you can sue him and whether it is worth it, in case he refuses to join.

Considerations for Agreement Flexibility
If you are looking at either party having the right to back out, why even have an agreement? Just send a letter saying you like his profile/skills, etc., and would like to offer him a job in August 2023, and ask him to apply for the position at that time. In that case, if he applies and you don't want to give him a job, then it's okay because he is applying then.
