Anyone know what I should check (if anything)?

Its not yet 3yrs old (albeit with 110k miles)  
It sputters every other day - when idling - starting almost a month ago (its died twice)

Nothing else is wrong.

No lights are on - regular oil/filter changes - just inspected.  
🤷🏼‍♀️

Plugs should be changed @ 100,000 miles. Only get the Denso part number in the manual, not an equivalent Very easy to change Also change the air filter

Time to clean the throttle body?

I agree with both above, have you changed the spark plugs with the correct ones and NOT from Amazon or eBay (both have lots of fakes), buy from a local parts store or the dealer only (for Toyota/Lexus anyway)…

Has the throttle body been properly cleaned??  
I would even go as far as to look at the TPS (throttle position sensor) % at idle in live data to see what it is reading…  
Here is a video explaining why and how to clean it…

What the other guys have said should be checked . This is also important if you happen to run the cheapest non top tier gas you can find .
