Seduce Grimmy

Yup. Unfortunately, it has only 10% success chance. 20% if your sim is very flirty. So, I'd avoid it.

Fun fact about pleading: there are 4 emotional pleads in the game:

• Demanding Grim to Spare the dying sim - can be done by confident sims. 40% success rate, 50% if very confident.
  
• Seducing Grim to spare the dying sim - :)
  
• Wail to Grim Reaper to spare the dying sim - can be done by sad sims. 30% success rate (33% for gloomy sims), 40% for very sad sims (36% for gloomy sims)
  
• Yell at death - can be done by angry sims. Always fails, so avoid it

So yeah, not the best option, but better than yelling. Demanding the Grim Reaper is the best option (as normal plead has 33% success rate).

My sim self's middle son Andrew recently died and his husband Riku had an opportunity to seduce Grim to spare Andrew but Grim refused and still took him.

That's terrible! But was Riku Andrew's husband, or your simself's? Couldn't tell from how it was worded. Very interesting story event!
