I signed up for the AA corporate challenge a while back, and recently noticed the challenge is about to expire—only to realize I hadn't earned enough LP yet. So I scrambled to start, with the goal of 10,000 LP to keep Gold.

T-Mobile 5G Home Internet $30–60 3,700 0.81–1.62 Must stay active 60 days; new customers only, whether existing accounts count as new is unverified
Broadband (Verizon Business / T-Mobile Fiber / Verizon Home) Unverified 7,400 / 5,600 / 4,500 0.68–1.33 Book value; gated by business eligibility and coverage respectively, Verizon Home expires 11/4

Prepaid hotel (AAdvantage Hotels) method
I haven't tried this one. AAdvantage Hotels base miles count 1:1 toward LP (paid boosts don't count), activity date is based on check-in date, cap of 15,000 LP per transaction. Prepaid No Show has DP for points. Bangkok WiNNiNE one booking ~14,300 points @4.17¢, or Vegas Fontainebleau also works
Getting 1,300 LP for $7.50 is genuinely cheap, but it's limited to once per account—if you want to farm more, you'll need to switch accounts or find another route. I'd suggest knocking out the low-barrier ones like Lyca and pdfFiller first, then focusing your effort on the big-ticket ones like Motley Fool, otherwise you won't have enough time.
