Restricting tools like web search, dns record search is futile. Who are you trying to protect here? the average user who does not care about security and just wants to get stuff done?
News flash, OpenAI, Anthropic and the US Gov can put all the restrictions they want but llms are already open source and in the hands of bad actors. The genie is out of the bottle.
It will be on users themselves to figure out how to use these systems in a safe manner.
