Several items in LOLCATS aren't translated from English.
The items and areas I personally was able to find such were:

minecraft:red_sand
minecraft:oak_button
minecraft:book
'Redstone' creative tab

There are other items which may want to be translated in preference, but still are 'translated' into LOLCATS regardless, these being:
minecraft:rabbit (Bloody Jumpin Foodz)
minecraft:nether_bricks (Brik from hell)
minecraft:acacia_fence (Cat Fence [LF Box Unicode]) (Image provided for clarity)
