Contracts (which is what I assume you're talking about) are only "boilerplate" in fair-weather deals. But if literally anything goes wrong during the escrow period, then the wording of that contract suddenly becomes critical. When tens of thousands of dollars are at stake, I'd never rely on AI-generated output.
That being said, I also agree with you as for the value of agents, because they're the ones who write these contracts and to be honest, most of them are pretty stupid. We really need real estate lawyers to be drafting these things, not relying on templates. A good contract is worth a hefty fee.
Most offers in the US are truly boilerplate, the text being provided by an association of real estate agents, and the wording is not customizable. This of course does depend on your state.
Contracts aren't worth much more than the paper they're on if you're not willing to litigate, and there's precious few cases where you'd want to. Most of the time you should just resolve your dispute by blowing up the transaction. Speaking from experience and having hired the lawyers to originally draft things, you really have no other remedy if the other party really wants to breach.
I wouldn't want to use a realtor for land worth more than 50k though. Use the percentage commission to work for you not against you.
