The thing is the lore team had lots of internal difficulties around the time when they retconned the old lore.
They tried to change the lore format,starting with vel'koz they started to do more story-like lore(nowadays called color text) instead of bios.
Then when the Shurima event happened,they tried to put short-lores into the ingame client,while putting the full lores on the official page.
However that failed due to technical difficulties,resulting in some champs being stuck with just their short lore.
They released some lore pieces here on the boards as a short term solution and tried different things with the following champs,meaning that
and
being stuck with only their short lore and some additional "lore piece" on the official site(that are nowadays hard to find,which is why i recommend the wiki),Rek'sai got a journal of someone trying to capture her,Bard got a video and a teaser site,Ekko got a comic and his video and TK got the video from above.
Then around the time of the bilgewater event they solved some of the problems and introduced the current lore format,which basically means that a champion has a short lore in the client and a full bio AND a color text somewhere on the main page.
These full lores can be found on the respective champion pages and pretty much from then on every new/reworked champion,as well as those related to the bilgewater and harrowing event got new lores(
have full lores on their champion pages).
However their approach changed again during the Mt.Targon lore update(appearantly there were more coding problems with the official site),leading to a new approach for the lore team where they put the new lores for all the targon champs on a seperate page and later they did the same for the shurima champs.
These lores can be found here
