First of all, your in the wrong forum "Minecraft: JAVA EDITION", you should have posted in the PS4 forum threads, but anyways, on to the question being answered.
While I've played the Xbox versions but it was a while ago, all console versions use the same menus and only differ by buttons so it shouldn't be too different or difficult for me to answer.
I think I remember the Lapis block being uncrafted in the 'dyes' section or 'other materials' tab of crafting menu of the console versions (meaning I think its the last tab of the crafting menu and maybe the left side more so than the right side of the recipes in that section of the menu/tab. That's from memory though. I'm pretty sure it hasn't changed too much since I last played the console versions of the game which was a while ago/2 years ago I think and have played the Java Edition since so I can only remember so much.
This was me not considering the Java Edition like/Old School you work it by the blocks in the right slots of the crafting grid, compared to the 'select whatever crafting recipe you want' type that Legacy Console has been known for/commonly has that is more accessible to those. I don't know about the console versions very well so excuse me on my lack of knowledge of them these days.
I hope that helps.
