It may not be laziness, but it is definitely entirely lacking in empathy.

Using AI reflexively assumes that you have a tool that they do not, or that they are not motivated or smart enough to use before coming to you. LMGTFY is directly a laziness-rebuff for this reason - everyone has and already uses google. Why would you assume that your coworkers are lazy or not smart as a first step in any interaction?

There are millions of reasons a genuine conversation should happen when a coworker reaches out, and many of these, if exercised in good faith, would be a trust-building interaction. LMGTFY and AI copypasta both are snide, cost-free rebuffs of a coworker who approached you with a question - and that's just shit culture if it becomes common.

I’m using ai to answer questions, but I instruct it in draft what answers to include, what info to include from my llm wiki (second brain). Saves time to write a correct response, can easily refer to past conversations, but definitely not 100% outsources to AI.
