A few thoughts in general re: assisted living... not all relating to the OP's situation.
First... LTC policies... not all the same. While ours provides for $100/day, the actual cost of assisted living in a facility, is closer to $200 to $300 per day. In our case, the LTC policy goes for a maximum of five years. As an alternative, the total money can be used for home care... up to $150/day up to the maximum payout.
Home care assistnce. In our area, both of these services charge $22/hour. If fortunate enough to have reasonable health, private personal help is usually closer to $10-$15/hr. Live in help is another possibility... not easy to find.
I Believe that medicare pays for three months care... but this must be ordered by a doctor.
About medicaid. One thing to be careful of... the five year lookback. Medicaid is available when assets are depleted to a certain level. Before this kicks in, there is a five year lookback to be sure thatwhatever assets that were available 5 years ago, were not unusually reduced by means of a gift of dollars or property. This is a very serious violation of the law.
One possibility.... that we've seen used in our CCRC... Children of those who will be expected to need assisted living in the immediate future, have contacted our assisted living facility, and been placed on the waiting list... paying one month's rent to assure a reasonably short wait. The size of our facilities means a reasonbly fast turnover.. people going to other parts of the
CCRC... rehab, Alzheimers or nursing home. So far, management has been very flexible, if there is no waiting list.
Most important...that has been discussed... not to wait. Do the homework about facilities, upfront. This means spending some time in the prospective facility to see the cleanliness , the food, the staff, and long enough to talk to some patients.
What with all of the warnings, an upside... We have lived in our CCRC for 15 years in a regular home, but have no fear of moving to whatever part of the campus that maybe necessary.
One possibility that hasn't been discussed here. Nearby, there is a "home" named "Simple Comfort... that offers housing for about 8 to 10 older persons.
From what I've seen, the people are happy and seem well cared for, but while old, are probably qualified for "independent living". Meals, washing, housekeeping and basic needs are provided, and there are even a few wheelchairs. Most facilities... living room, card rooms etc are "shared"., and rooms are for one or two persons. "Independent Living" is a formal qualification. Some info here... different for local legislation.

The changeover need not be traumatic. Some early research to become famiiar with the options should make the process easier on you and your parents.
Good luck!
