Here's the video:

It's nothing fancy and there's a bit of down time but that's mostly due to it being not refined at all. Thoughts for improvement:

• Skip/shorten the farming part
• Get more armor early
• Drag waves into bushes to delay them instead of stacking
• Use red buff duration better
• Exploit Soraka/Shen Ults better

If you want to lose fast, you can't afford to sit back and wait though, that takes forever (assuming it's even possible since it seems like your bots are a stronger by default).

Idk if there are better strategies, but this seems to work fairly well:

• Get a couple of kills and cs early in mid and top to afford items (as well as turret platings, but only on mid)
• Buy Tabi and as much lifesteal as possible
• Clear enemy krugs to reset their level
• Do the enemy red buff for extra lifereg
• Stack enemy waves on the toplane by healing off of krugs and caster minions
• Release waves as soon as blue waves crash into top turret to increase the bounce back
• By getting to low hp you force Soraka and shen ults, which slows down the push on bottom lane since it's a 1v2

Essentially, it all comes down to how well you can balance your hp while needing as few items as possible to sustain

I'd like to create a new category where you try to lose the tutorial as fast as possible. My first attempt is 21 minutes but I'm sure it can be optimized by a lot.

You can't lose the first part, but you can lose part 2 and 3
