The Elland Road club is keen on the Red defender following their relegation from the Premier League.
Phillips helped Bournemouth seal promotion back to the top flight last season during a loan spell at the south club coast, and now could be set for another move down to the second tier.
According to The Athletic, Leeds are keen on the centre-back who is valued at around £10million by Liverpool.
Phillips’ contract at Anfield runs until 2025.
