I want to make a LWC which input keywords and show the results on list using lightning-layout & lightning-layout-item. And I want to make it that doesn't depend on SObjects.

Now, I have a problem the list. it inputs any keywords doesn't show anything. html is below;

    <lightning-layout>
        <lightning-layout-item flexibility="auto" padding="around-small">
            <lightning-input
                type="search" label=""
                name="search-key"
                placeholder="Input Name for Search"
                onchange={handleSearchKeyChanged} 
                value={searchKey}>
            </lightning-input>
        </lightning-layout-item>
    </lightning-layout>

    <div class="slds-m-around_small">
        <lightning-layout multiple-rows="true" draggable="true">
            <template if:true={searchResult} for:each={searchResult} for:item="row" key={row.id}>
                <lightning-layout-item key={row.id}>
                    <span>{row.name}, {row.detail}, {row.lastUpdate}</span>
                </lightning-layout-item>
            </template>
        </lightning-layout>
    </div>

and here is JS;

searchKey = '';
searchedResult = {};

handleSearchKeyChanged(e) {
    window.clearTimeout(this.delayTimeout);
    const searchKey = e.target.value;
    this.delayTimeout = setTimeout(() => {
        this.searchKey = searchKey;
    }, DELAY);
}

@wire(getSearchedList, {searchKey: '$searchKey', selectSObj: '$selectedSObj'})
getSearchedListResult({error, data}) {
    if (data) {
        this.searchedResult = JSON.parse(data);
        console.log('>>> searchResult: ', this.searchedResult);
            
    } else if (error) {
        this.error = error;
    }
};

console.log in getSearchedListResult, it shows data. It worked when I use lightning-datatable, but it can't use for my reason.

I think it's similler question is here but it looks unresolved: Lightning Web Component - passing object between component

In your markup, you use searchResult, but in your JS, you use searchedResult. This is likely what's causing your problem.

Also, your searchResult should be an array, not an object:

searchResult = []; // not {};
